Description

Technical Field

[0001] The present disclosure relates to the technical field of target tracking, and in particular to a track association method, device and equipment based on multiple radiation sources. Background Art

[0002] The demand for real-time monitoring and tracking of targets at sea is increasing. Passive detection systems do not need to actively radiate electromagnetic waves, so they naturally have the characteristics of high concealment, strong anti-interference ability, and long range. As an important part of the passive detection system, satellite-borne passive detection has the advantages of large detection range, rich information acquisition, and no influence from weather conditions. It has become an important means of perceiving distant targets.

[0003] In the process of realizing the present disclosure, the inventors found that in the related technologies, the electromagnetic parameters of the radiation source acquired by satellite-borne passive detection are not fully utilized, and the target association tracking of current satellite-borne passive detection mainly processes the identified targets. Since there are still a large number of unidentified targets, track fragments exist and the continuity is poor, making it difficult to accurately monitor and track targets at sea.

[0029] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0030] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0031] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0032] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0033] In the technical solution of the present disclosure, the user information (including but not limited to user personal information, user image information, user device information, such as location information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved are all information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with relevant laws, regulations and standards, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0034] In the process of realizing the present disclosure, it is found that satellite-borne passive detection has become an important means of perceiving distant targets due to its advantages such as large detection range, rich information acquisition, and no influence from weather conditions. The satellite-borne passive detection system receives radar, communication and other radiation source signals assigned to maritime targets, and obtains the location, electromagnetic parameters and radiation source model and other attribute information of the target radiation source after data processing. The satellite-borne passive detection system directly obtains the information of the radiation source assigned to the target. Since the same target may have multiple radiation sources and multiple radiation sources may be dynamically switched on and off, the track of the same maritime mobile target may present multiple single signal fragment tracks with different phases, inconsistent attribute content and different precision, which leads to challenges in the associated tracking of densely moving targets at sea. In the related art, the multi-target tracking method is mainly used in the field of radar target tracking, which relies on the spatiotemporal position information of the target. In the field of satellite-borne passive detection, the spatiotemporal position information has large errors, and it is easy to have association ambiguity in dense target scenes by relying only on spatiotemporal association, and satellite-borne passive detection can obtain electromagnetic signals and parameter information of radiation sources, which has not been fully utilized. In addition, the target association tracking of satellite-borne passive detection in the existing technology mainly processes identified targets and uses target identification information to associate fragmented tracks. However, a large number of unknown target tracks are not automatically processed, and the fragments exist in isolation, with poor track continuity. It is also difficult to identify unknown targets, and it does not support automatic iterative updates of the situation. It relies on prior information and subsequent manual analysis, and has poor processing timeliness.

[0035] In view of this, an embodiment of the present disclosure provides a track association method based on multiple radiation sources, including: acquiring single-signal track information, wherein the single-signal track information represents information sent by a single radiation source, and multiple radiation sources are deployed on a target, and the target includes multiple targets; based on the single-signal track information, performing identity identification on the target to obtain a target identification result, wherein the target identification result includes an identified target or an unidentified target; performing target association on the identified track information and the unidentified track information to obtain an association result, wherein the identified track information represents the single-signal track information corresponding to the identified target, and the unidentified track information represents the single-signal track information corresponding to the unidentified target.

[0036] Figure 1 The application scenario diagram of the track association method based on multiple radiation sources according to an embodiment of the present disclosure is schematically shown.

[0037] like Figure 1As shown, the application scenario 100 according to this embodiment may include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, and a server 105. The network 104 is used to provide a medium for a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103, and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0038] The user can use the first terminal device 101, the second terminal device 102, and the third terminal device 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications can be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only for example).

[0039] The first terminal device 101, the second terminal device 102, and the third terminal device 103 may be various electronic devices having display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0040] The server 105 may be a server that provides various services, such as a background management server (only as an example) that provides support for websites browsed by users using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server may analyze and process the received data such as user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0041] It should be noted that the track association method based on multiple radiation sources provided in the embodiment of the present disclosure can generally be executed by the server 105. Accordingly, the track association device based on multiple radiation sources provided in the embodiment of the present disclosure can generally be set in the server 105. The track association method based on multiple radiation sources provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Correspondingly, the track association device based on multiple radiation sources provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105.

[0042] It should be understood that Figure 1The number of the first terminal device, the second terminal device, the third terminal device, the network and the server in the embodiment is only for illustration. According to the implementation requirements, there may be any number of the first terminal device, the second terminal device, the third terminal device, the network and the server.

[0043] Figure 2 The flowchart of the track association method based on multiple radiation sources according to an embodiment of the present disclosure is schematically shown.

[0044] like Figure 2 As shown, the track association method 200 based on multiple radiation sources of this embodiment includes operations S210 to S230.

[0045] In operation S210, single signal track information is acquired.

[0046] In operation S220, the target is identified based on the single signal track information to obtain a target identification result.

[0047] In operation S230, target association is performed on the identified track information and the unidentified track information to obtain an association result.

[0048] According to the embodiments of the present disclosure, the target may be an object that needs to be detected, identified and tracked in the marine environment, mainly including ships, unmanned boats, submarines, buoys, etc. Therefore, the target may also be referred to as a maritime target. The target may include multiple targets. For example, the target may be a fleet of 10 ships. The radiation source may represent a device or natural phenomenon that can emit electromagnetic waves or ions. Multiple radiation sources, that is, multiple radiation sources, refer to the same target being equipped with multiple different radiation sources such as radar, communication, friend-or-foe identification, data link, etc. Each radiation source emits an electromagnetic wave signal according to its working task. After the signal is received by the satellite-borne passive detection system, the signal is processed to obtain the radiation source position and parameter information. The radiation source track information can be obtained according to a certain beat processing, and the subsequent track association fusion is performed based on this.

[0049] According to an embodiment of the present disclosure, the single signal track information can represent the information sent by a single radiation source, and multiple radiation sources can be deployed on a target. The single signal track information may include the current position of the target, the time when the target is at the current position, the electromagnetic parameters of the target, and the attribute information of the radiation source. For example, the electromagnetic parameters of the target may be the carrier frequency, pulse width and other information of the single signal track information. The attribute information of the radiation source may include the identity information of the target and the identity information of the radiation source. For example, the identity information of the target may be the number information of the target, and the identity information of the radiation source may be the model information of the radiation source. In the case where the identity information of the target is included in the attribute information of the radiation source, the single signal track information may be considered as the identified track information. In the case where the identity information of the target is not included in the attribute information of the radiation source, the single signal track information may be considered as the unidentified track information.

[0050] According to an embodiment of the present disclosure, a recognized target can be characterized as a known target, that is, the identity information of the target is clear. For example, the serial number of the target is known. An unrecognized target can be characterized as an unknown target, that is, the identity information of the target is unclear, for example, the serial number of the target is unknown. The target recognition result may include a recognized target or an unrecognized target.

[0051] According to an embodiment of the present disclosure, the identified track information can represent the single signal track information corresponding to the identified target, that is, the identified track information can be the track information of the identified target. The unidentified track information can represent the single signal track information corresponding to the unidentified target, that is, the unidentified track information can be the track information of the unidentified target.

[0052] According to an embodiment of the present disclosure, the association result may include an association result between the identified track information and the target and an association result between the unidentified track information and the target. The association result may be obtained by performing target association on the identified track information and the unidentified track information.

[0053] According to the embodiments of the present disclosure, for the identified track information, it can be associated with the identified target first, and when the association with the identified target fails, it can be associated with the unidentified target. For the unidentified track information, it is necessary to associate with both the identified target and the unidentified target.

[0054] According to an embodiment of the present disclosure, by identifying the target based on the acquired multiple single-signal track information, a target identification result can be obtained, and then the identified track information and the unidentified track information are target associated to obtain an association result. Since target association is performed not only for the identified target but also for the unidentified track information, the continuous difference of track information caused by the existence of track information fragments is avoided, thereby improving the target tracking accuracy and continuity in multi-target scenarios.

[0055] According to an embodiment of the present disclosure, target association is performed on identified track information and unidentified track information to obtain an association result, including: associating the identified track information with the identified target and the unidentified target respectively to obtain a first association result of the identified track information; associating the unidentified track information with the identified target and the unidentified target respectively to obtain a second association result of the unidentified track information.

[0056] According to an embodiment of the present disclosure, the identified track information may be single-signal track information corresponding to a preset identified target, or may be single-signal track information corresponding to other identified targets. For example, when the preset identified targets include target A, target B, target C, and target D, and the other identified targets include target F and target G, the single-signal track information corresponding to target A, the single-signal track information corresponding to target B, the single-signal track information corresponding to target C, the single-signal track information corresponding to target D, the single-signal track information corresponding to target F, and the single-signal track information corresponding to target G are all identified track information.

[0057] According to an embodiment of the present disclosure, the first association result of the identified track information may include successful association of the identified track information with the identified target, successful association of the identified track information with the unidentified target, or failure to associate the identified track information with both the unidentified target and the identified target.

[0058] According to an embodiment of the present disclosure, the successful association of the identified track information with the identified target can represent the match between the identified track information and the single-signal track information corresponding to the identified target. For example, the identity information of the target included in the identified track information is consistent with the identified target. The successful association of the identified track information with the unidentified target can represent the match between the identified track information and the single-signal track information corresponding to the unidentified target. For example, in the case where the identified track information is successfully associated with the unidentified target, the unidentified target can be determined based on the identity information of the target included in the identified track information, so that the unidentified target is converted into an identified target.

[0059] In one embodiment, when the preset identified targets include M identified targets and N unidentified targets, and the identified track information is successfully associated with the unidentified targets, the current identified targets may be M+1 and the unidentified targets may be N-1.

[0060] According to an embodiment of the present disclosure, the failure of the identified track information to be associated with both the unidentified target and the identified target can indicate that the identified track information fails to be associated with not only the unidentified target but also the identified target. For example, when the identity information included in the identified track information is target F, the identified target is target C, and the unidentified target is target not F, the identified track information fails to be associated with the identified target and fails to be associated with the unidentified target.

[0061] In one embodiment, when the preset identified targets include M identified targets and N unidentified targets, and the identified track information fails to be associated with both the unidentified targets and the identified targets, the current identified targets may be M+1 and the unidentified targets may be N, wherein the newly identified target is target F corresponding to the identified track information.

[0062] According to an embodiment of the present disclosure, the second association result of the unidentified track information may include successful association of the unidentified track information with the identified target, successful association of the unidentified track information with the unidentified target, or failure to associate the unidentified track information with both the unidentified target and the identified target.

[0063] According to an embodiment of the present disclosure, the successful association of unidentified track information with an identified target can indicate that the unidentified track information and the single signal track information corresponding to the identified target do not match. For example, the single signal track information corresponding to the identified target and the unidentified track information are inconsistent. The successful association of unidentified track information with an unidentified target can indicate that the unidentified track information and the single signal track information corresponding to the unidentified target match. For example, in the case where the unidentified track information is successfully associated with the unidentified target, the unidentified target can be tracked.

[0064] According to an embodiment of the present disclosure, the failure of associating the unidentified track information with both the unidentified target and the identified target can indicate that the unidentified information fails to associate not only with the unidentified target, but also with the identified target. For example, when the identified target is target C, and the identity information included in the unidentified track information is inconsistent with target C and is inconsistent with the unidentified target, the unidentified track information fails to associate with both the unidentified target and the identified target.

[0065] In one embodiment, when the preset identified targets include M identified targets and N unidentified targets, and the unidentified track information fails to be associated with both the unidentified targets and the identified targets, the current identified targets may be M, and the unidentified targets may be N+1, wherein the newly added unidentified target is the target corresponding to the unidentified track information.

[0066] According to an embodiment of the present disclosure, by associating identified track information and unidentified track information with unidentified targets and identified targets respectively, a first association result of the identified track information and a second association result of the unidentified track information can be determined, thereby updating the identity information of multiple targets, thereby improving the real-time and accuracy of the target identity information.

[0067] According to an embodiment of the present disclosure, the identified track information is associated with the identified target and the unidentified target respectively to obtain a first association result of the identified track information, including: when the identified track information belongs to a preset identified target, the identified track information is associated with the preset identified target to obtain a first intermediate association result of the identified track information; when the identified track information does not belong to the preset identified target, the identified track information is associated with the unidentified target to obtain a second intermediate association result of the identified track information.

[0068] According to an embodiment of the present disclosure, the first association result may include a first intermediate association result and a second intermediate association result.

[0069] According to an embodiment of the present disclosure, the preset identified targets may include multiple ones. The first intermediate association result may indicate that the identified track information is successfully associated with the preset identified target. In the case where the identified track information belongs to any one of multiple preset identified targets, the identified track information may be associated with the preset identified target to obtain the first intermediate association result of the identified track information. For example, in the case where the preset identified targets include target A, target B, target C and target D, and the identity information of the target included in the identified track information is target A, the identified track information may be associated with target A to track target A.

[0070] According to the embodiment of the present disclosure, since the first intermediate association result represents that the identified track information is successfully associated with the preset identified target, that is, the target corresponding to the identified track information can be tracked.

[0071] According to an embodiment of the present disclosure, the second intermediate association result may include that the identified track information is successfully associated with the unidentified target or that the identified track information fails to be associated with both the unidentified target and the identified target. In the case where the identified track information is successfully associated with the unidentified target, the identity information of the unidentified target can be confirmed. For example, when the identity information of the target included in the identified track information is target A, and the identified track information is successfully associated with the unidentified target, the unidentified target can be considered to be target A. In the case where the identified track information fails to be associated with both the unidentified target and the identified target, a new unidentified target can be newly approved. For example, when the identity information of the target included in the identified track information is target A, the identified target is target C, and the unidentified target is not target A, a new unidentified target can be approved, that is, a new unidentified target is added.

[0072] According to an embodiment of the present disclosure, when determining whether the identified track information belongs to an identified target, the identified track information can be associated with a preset identified target and an unidentified target, respectively, so as to determine a first intermediate association result and a second intermediate association result of the identified track information. In the process of determining the first intermediate association result and the second intermediate association result of the identified track information, the identity information of multiple targets can be updated, thereby further improving the real-time and accuracy of the target's identity information.

[0073] According to an embodiment of the present disclosure, the unidentified track information is associated with the identified target and the unidentified target respectively to obtain a second association result of the unidentified track information, including: associating the unidentified track information with the identified target to obtain a third intermediate association result of the unidentified track information; associating the unidentified track information with the unidentified target to obtain a fourth intermediate association result of the unidentified track information.

[0074] According to an embodiment of the present disclosure, the second association result may include a third intermediate association result and a fourth intermediate association result.

[0075] According to an embodiment of the present disclosure, the third intermediate association result can represent that the unidentified track information is successfully associated with the identified target. When the unidentified track information is successfully associated with the identified target, the identified target can be tracked. For example, when the identified target is target C and the unidentified track information is successfully associated with the identified target, the unidentified track information can be considered to be the single signal track information corresponding to the identified target, thereby tracking the identified target.

[0076] According to an embodiment of the present disclosure, the fourth intermediate association result may include that the unidentified track information is successfully associated with the unidentified target or that the unidentified track information fails to be associated with both the unidentified target and the identified target. In the case where the unidentified track information is successfully associated with the unidentified target, the tracking of the unidentified target can be achieved. In the case where the unidentified track information fails to be associated with both the unidentified target and the identified target, it can be considered that the unidentified track information fails to be associated not only with the unidentified target, but also with the identified target, thereby adding an unidentified target corresponding to the unidentified track information.

[0077] According to an embodiment of the present disclosure, by associating unidentified track information with identified targets and unidentified targets respectively, a third intermediate association result and a fourth intermediate association result of the unidentified track information can be determined. In the process of determining the third intermediate association result and the fourth intermediate association result of the unidentified track information, the identity information of multiple targets can be updated, thereby further improving the real-time and accuracy of the target's identity information.

[0078] According to an embodiment of the present disclosure, the above-mentioned track association method based on multiple radiation sources also includes: obtaining a comprehensive correlation degree based on single signal track information and identified track information; and determining an association result based on the comprehensive correlation degree, preset identity attribute rules and preset affiliation relationship rules.

[0079] According to an embodiment of the present disclosure, a comprehensive correlation is obtained based on single-signal track information and identified track information, including: calculating the correlation between the spatiotemporal position information in the single-signal track information and the spatiotemporal position information in the identified track information to obtain a first correlation related to the spatiotemporal position information; calculating the correlation between the electromagnetic parameter information in the single-signal track information and the electromagnetic parameter information in the identified track information to obtain a second correlation related to the electromagnetic parameter information; and determining the comprehensive correlation based on the first correlation and the second correlation.

[0080] According to an embodiment of the present disclosure, in the track association process, one single-signal track information is associated with one identified track information at a time, and this process is repeated, so that multiple single-signal track information of multiple targets are polled by this association process, completing the association of all single-signal track information.

[0081] According to an embodiment of the present disclosure, both the single-signal track information and the identified track information may include spatiotemporal position information and electromagnetic parameter information. Since whether there is time overlap between the single-signal track information and the identified track information is considered, the multi-signal track information is automatically sequentially associated and fused in time sequence. In the case where the single-signal track information and the identified track information have time overlap or do not have time overlap, the correlation degree related to the spatiotemporal position can be calculated to obtain the first correlation degree related to the spatiotemporal position information, wherein the first correlation degree related to the spatiotemporal position information may include a first correlation degree with time overlap and a first correlation degree without time overlap. The first correlation degree with time overlap and the first correlation degree without time overlap may be different.

[0082] According to an embodiment of the present disclosure, in the case where the single-signal track information and the identified track information have time overlap, the temporal and spatial position information in the single-signal track information and the temporal and spatial position information in the identified track information are subjected to a correlation calculation related to the temporal and spatial position, and a first correlation with the temporal and spatial position information having time overlap is obtained. In the case where the single-signal track information and the identified track information do not have time overlap, the temporal and spatial position information in the single-signal track information and the temporal and spatial position information in the identified track information are subjected to a correlation calculation, and a first correlation with the temporal and spatial position information having no time overlap is obtained. In the case where the single-signal track information and the identified track information do not have time overlap, the single-signal track information and the identified track information can also be extrapolated.

[0083] According to an embodiment of the present disclosure, in the case where the single signal track information and the identified track information have time overlap or do not have time overlap, the correlation degree related to the electromagnetic parameter information can be calculated to obtain a second correlation degree related to the electromagnetic parameter information, wherein the second correlation degree related to the electromagnetic parameter information may include a second correlation degree with time overlap and a second correlation degree without time overlap. The second correlation degree with time overlap and the second correlation degree without time overlap may be different.

[0084] According to an embodiment of the present disclosure, when the single signal track information and the identified track information have time overlap and originate from the same radiation source, the electromagnetic parameter information in the single signal track information and the electromagnetic parameter information in the identified track information are correlated with the electromagnetic parameter information to obtain a first correlation with the electromagnetic parameter information and having time overlap. When the single signal track information and the identified track information do not have time overlap and originate from the same radiation source, the electromagnetic parameter information in the single signal track information and the electromagnetic parameter information in the identified track information are correlated to obtain a first correlation with the electromagnetic parameter information and having no time overlap. When the single signal track information and the identified track information do not have time overlap, the electromagnetic parameter information in the single signal track information and the identified track information can also be inferred and predicted.

[0085] According to the embodiments of the present disclosure, except for the cases where the single signal track information and the identified track information originate from the same radiation source, with or without time overlap, all other cases belong to heterogeneous electromagnetic radiation sources, and heterogeneous electromagnetic radiation sources do not need to perform correlation calculation related to electromagnetic parameter information.

[0086] According to an embodiment of the present disclosure, the comprehensive correlation degree may be determined according to the first correlation degree, the second correlation degree and a preset weighting coefficient, as shown in the following formula (1).

[0087] (1)

[0088] in, Represents the comprehensive correlation, represents the first degree of association, represents the second degree of association, represents the first preset weighting coefficient, represents the second preset weighting coefficient.

[0089] According to an embodiment of the present disclosure, the preset weighting coefficient may include a first preset weighting coefficient and a second preset weighting coefficient, and the first preset weighting coefficient and the second preset weighting coefficient may be determined according to an application scenario and data conditions.

[0090] According to an embodiment of the present disclosure, an association result is determined according to a comprehensive association degree, a preset identity attribute rule and a preset affiliation relationship rule, including: based on at least one of the preset identity attribute rule and the preset affiliation relationship rule, an intermediate association result is determined according to single signal track information and identified track information; when the intermediate association result indicates that the intermediate association result is uncertain, the association result is determined according to the comprehensive association degree and the preset association degree.

[0091] According to an embodiment of the present disclosure, the preset identity attribute rule may be an identity attribute rule set based on experience. For example, in the case where the single-signal track information and the identified track information do not belong to targets in the same area, it can be considered that the single-signal track information and the identified track information do not satisfy the preset identity attribute rule, that is, the association between the single-signal track information and the identified track information fails. The preset affiliation relationship rule may be an affiliation relationship rule set based on experience. For example, when the single-signal track information is information sent by radiation source 1, the identified track information is information sent by radiation source 11, and radiation source 1 and radiation source 11 are not deployed on the same target, it can be considered that the single-signal track information and the identified track information do not satisfy the preset affiliation relationship rule, that is, the association between the single-signal track information and the identified track information fails.

[0092] According to an embodiment of the present disclosure, an intermediate association result can be determined based on at least one of a preset identity attribute rule and a preset affiliation relationship rule according to the single signal track information and the identified track information. For example, the intermediate association result can be determined based on whether the single signal track information and the identified track information meet the preset identity attribute rule. For another example, the intermediate association result can be determined based on whether the single signal track information and the identified track information meet the preset affiliation relationship rule.

[0093] According to an embodiment of the present disclosure, when the intermediate correlation result indicates that the intermediate correlation result is uncertain, that is, when the single signal track information and the identified track information may be successfully correlated or may fail to be correlated, the correlation result can be determined based on the comprehensive correlation degree and the preset correlation degree. For example, if the single signal track information is unidentified track information, the single signal track information and the identified track information may be successfully correlated or may fail to be correlated, and then the correlation result can be determined based on the comprehensive correlation degree and the preset correlation degree.

[0094] According to an embodiment of the present disclosure, the association result may include association success or association failure. The preset association degree may be set according to demand or experience. For example, when the preset association degree may be 85% and the comprehensive association degree is greater than 85%, it may be considered that the single signal track information is successfully associated with the identified track information. For another example, when the preset association degree may be 85% and the comprehensive association degree is less than or equal to 85%, it may be considered that the single signal track information is failed to be associated with the identified track information.

[0095] According to an embodiment of the present disclosure, by calculating the correlation between the spatiotemporal position information and the electromagnetic parameter information in the single-signal track information and the identified track information, a first correlation related to the spatiotemporal position information and a second correlation related to the electromagnetic parameter information can be obtained. Then, based on the first correlation and the second correlation, a comprehensive correlation can be determined. By polling multiple single-signal track information and the identified track information, the comprehensive correlation of all single-signal track information and other single-signal track information can be determined. Then, the comprehensive correlation is compared with the preset correlation to determine the correlation result, thereby improving the accuracy of the obtained correlation result.

[0096] Figure 3 The flowchart of determining the association result according to the embodiment of the present disclosure is schematically shown.

[0097] like Figure 3 As shown, according to the spatiotemporal position information 301 of the single signal track information and the identified track information, a first correlation 302 related to the spatiotemporal position information can be calculated. According to the electromagnetic parameter information 303 of the single signal track information and the identified track information, a second correlation 304 related to the electromagnetic parameter information can be calculated. By weighted summing the first correlation 302 and the second correlation 304, a comprehensive correlation 305 can be obtained. The intermediate association result 310 can be obtained not only by making an association decision based on the identity identification information 306 possessed by the single signal track information and the identified track information, combined with the preset identity attribute rule 307, but also by making an association decision based on the preset assignment information 308 possessed by the single signal track information and the identified track information, combined with the preset assignment relationship rule 309. It is judged whether the intermediate association result is certain 311. When the intermediate association result 311 indicates that the intermediate association result is uncertain, the comprehensive association degree 305 and the preset association degree are compared to determine the association result 312. When the intermediate association result 311 indicates that the intermediate association result is certain, the association result 312 is directly obtained.

[0098] According to an embodiment of the present disclosure, the above-mentioned track association method based on multiple radiation sources also includes: when the association result indicates any one of the first intermediate association result, the third intermediate association result and the fourth intermediate association result, the position information of the target is updated to obtain an updated first situation; when the association result indicates any one of the second intermediate association result and the fourth intermediate association result, the identity recognition information and the position information of the target are updated to obtain an updated second situation.

[0099] According to an embodiment of the present disclosure, the first situation may include the identity recognition information and updated position information of the target. When the association result indicates a first intermediate association result, that is, when the identified track information is successfully associated with the preset identified target, the identified target can be tracked, and therefore, the identity recognition information of the target remains unchanged, and the position information of the target is updated, thereby obtaining an updated situation. When the association result indicates a third intermediate association result, that is, when the unidentified track information is successfully associated with the identified target, the identified target can be tracked, and therefore, the identity recognition information of the target remains unchanged, and the position information of the target is updated, thereby obtaining an updated situation.

[0100] According to an embodiment of the present disclosure, since the fourth intermediate association result may include two situations: the unidentified track information is successfully associated with the unidentified target, or the unidentified track information fails to be associated with both the unidentified target and the identified target, when the fourth intermediate association result is that the unidentified track information is successfully associated with the unidentified target, the unidentified target can be tracked. Therefore, the identity identification information of the target remains unchanged, and the position information of the target is updated, so that the updated situation can be obtained.

[0101] According to an embodiment of the present disclosure, the second situation may include the updated identity recognition information and updated location information of the target. Since the second intermediate association result includes two situations: the identified track information is successfully associated with the unidentified target or the identified track information fails to be associated with both the unidentified target and the identified target, in both situations, the target's identity recognition information and location information can be updated, thereby obtaining an updated situation. In the case where the fourth intermediate association result is that the unidentified track information fails to be associated with both the unidentified target and the identified target, the target's identity recognition information and location information can be updated, thereby obtaining an updated situation.

[0102] According to the embodiments of the present disclosure, the situation of the target is updated differently when the association results are different, thereby realizing automatic iterative update of the situation, continuously tracking identified targets and unidentified targets, avoiding the problem of poor processing timeliness caused by relying on prior information or subsequent manual analysis in related technologies, and making the situation of the target gradually accurate and continuous after multiple complementary verifications of single-signal track information.

[0103] Figure 4 The flowchart of a track association method based on multiple radiation sources according to another embodiment of the present disclosure is schematically shown.

[0104] like Figure 4As shown, multiple different radiation sources such as radar 4011, communication 4012, and friend-or-foe identification 4013 are deployed on the same target. The multiple different radiation sources respectively send single signal track information 402, and determine whether the single signal track information has target identification information 403. If it has target identification information, that is, the target corresponding to the single signal track information is an identified target, determine whether the identified target belongs to a preset identified target 404. If the identified target belongs to the preset identified target, track the preset identified target 405. At this time, the identified targets are still M, and the unidentified targets are still N; if the identified target does not belong to the preset identified target, the single signal track information is associated with the N unidentified targets 406. If the identified track information is successfully associated with the unidentified target, the identity of the unidentified target is identified 407, so that the unidentified target is called an identified target. At this time, the identified targets are M+1 and the unidentified targets are N+1. If the identified track information fails to be associated with the unidentified target, a new identified target is started 408, that is, a new identified target is added. At this time, the identified targets are M+1 and the unidentified targets are N. If there is no target identification information, that is, the target corresponding to the single signal track information is an unidentified target, association is performed 409 with M preset identified targets and N unidentified targets respectively. If the association with the preset identified target is successful, Under this condition, the tracking of the preset identified target is realized 405. At this time, the identified targets are still M, and the unidentified targets are still N. When the association with the unidentified targets is successful, the tracking of the unidentified targets is realized 410. At this time, the identified targets are still M, and the unidentified targets are still N. When the association with the preset identified targets fails, and the association with the unidentified targets fails, a new unidentified target is batched 411. At this time, the identified targets are still M, and the unidentified targets are N+1. Through each association result, the track information fusion 412, the identity attribute information fusion 413 and the comprehensive identity identification of the unidentified targets 414 can be realized, and the situation can be iteratively updated to obtain a new situation 415, so as to iteratively poll, thereby realizing the iterative update and gradual refinement of the target's track information and identity identification information. Among them, the comprehensive identity identification of the unidentified targets 414 is realized based on the comprehensive correlation, the preset identity attribute rules and the preset affiliation relationship rules.

[0110] According to an embodiment of the present disclosure, establishing a sequential correlation fusion processing flow includes constructing a current situation including M preset identified targets and N unidentified targets, and correlating the single signal track information of a certain radiation source formed by real-time detection with the identified track information and the unidentified track information in the current situation to obtain a correlation result. Based on the correlation result, tracking of identified targets, tracking of unidentified targets, identification of unidentified targets, new batching of identified targets and new batching of unidentified targets are realized.
