Abstract
Description
Technical Field
[0001] The present application relates to the technical field of data processing, and particularly to a target recognition method and a dual-band millimeter-wave composite fuse. Background Art
[0002] When a proximity fuse approaches a target, the inductive sensing device of the fuse senses target information based on certain inherent characteristics of the physical fields (such as electromagnetic fields, light intensity fields, sound fields, electrostatic fields, pressure fields, and magnetic fields, etc.) of the target and its surrounding environment, or certain changes in the physical fields around the target caused by the appearance of the target, and transmits the sensed information to the signal processing device.
[0003] The signal processing device amplifies, screens, and discriminates the received signal, distinguishes target information from the complex signals, extracts characteristic quantities such as the target position, moving speed, and moving direction reflected by the target information, and finally the execution device outputs a start signal, and the execution device then outputs a detonation signal to the explosion sequence, causing the electric initiation element in the explosion sequence to fire and detonating the charge of the warhead to complete the mission of the fuse.
[0004] The proximity fuse is installed in the aircraft. At the end of the process of approaching the target, the aircraft needs to face a complex electromagnetic environment, which requires the aircraft to have sufficient anti-interference ability and continuous target tracking ability. Because during the flight process of approaching the target, the aircraft needs to fly at low altitude and maintain radio silence to avoid being detected when communicating with the outside world.
[0005] For the suppression of aircraft, the current means include radio interference, radio deception, and radio retardation, etc. In the absence of external guidance, the proximity fuse in the aircraft needs to have stronger target tracking ability and anti-interference ability to cope with the increasingly complex usage environment.

[0058] To understand the technical solutions in this application more clearly, the related technologies are introduced.
[0059] Radio interference: In the process of radio communication, some electromagnetic energy enters the receiving system or channel through direct coupling or indirect coupling methods, resulting in a decrease in the quality of the useful received signal, errors or loss of information, and even the phenomenon of blocking communication.
[0060] Radio deception: An electronic interference that causes enemy electronic information equipment to receive false information, resulting in wrong judgments and wrong actions. According to the deception method, it can be divided into camouflage deception, simulation deception, and impersonation deception.
[0061] Radio jamming: The principle of blocking interference is that when there is a very strong interference signal in the outside world, although it does not cause intermodulation, co-frequency, or adjacent-frequency interference in terms of frequency, after acting on the front-end circuit of the receiver, due to the non-linearity of the receiver, it can still cause a decrease in the gain of the useful signal (being suppressed) or an increase in noise, resulting in a decrease in the sensitivity of the receiver.
[0062] The following further elaborates on the technical solutions in this application in conjunction with the accompanying drawings.
[0063] This application uses millimeter waves of two wavelengths to scan the tracking target. The advantages of millimeter waves are high bandwidth, low latency, and high data rate. During the process of scanning the tracking target, more millimeter waves can be sent and more feedback waves can be obtained within a unit time. During the approach flight process, the tracking target can be scanned more frequently, and a more accurate moving attitude of the tracking target can be obtained.
[0064] The target recognition method disclosed in this application is applied to the controller of the proximity fuse inside the aircraft. Please refer to Figure 1 , the target recognition method disclosed in this application includes the following steps:
[0065] S101, in response to the acquired trigger signal, start the proximity detection mechanism, use the first transmission channel to transmit the first millimeter wave, and use the second transmission channel to transmit the second millimeter wave. The wavelengths of the first millimeter wave and the second millimeter wave are different;
[0066] S102. Obtain a first feedback based on the first millimeter wave, and use the first feedback to obtain the target distance;
[0067] S103. Obtain a second feedback based on the second millimeter wave, and use the second feedback to obtain the target speed;
[0068] S104. Intermittently use the first transmission channel and the second transmission channel to generate a hybrid waveform to verify the target distance and the target speed; and
[0069] S105. Emit a detonation signal when the target distance meets the distance requirement;
[0070] Wherein, the wavelength of the first millimeter wave is not equal to the wavelength of the second millimeter wave;
[0071] In the time series, intermittently use the first millimeter wave to perform hybrid encryption on the second millimeter wave, and use the second millimeter wave to perform hybrid encryption on the first millimeter wave.
[0072] In step S101, the controller will obtain a trigger signal, and the generation methods of the trigger signal are as follows: generated by an external guiding signal; generated by a set instruction; generated by an analysis and processing device (such as an image sensor) carried by the aircraft itself. Of course, it can also be generated by a related device on the proximity fuse.
[0073] After receiving the trigger signal, first start the proximity detection mechanism. After the proximity detection mechanism is started, use the first transmission channel to transmit the first millimeter wave, and use the second transmission channel to transmit the second millimeter wave. The wavelengths of the first millimeter wave and the second millimeter wave are different, and the advantages of using the two millimeter waves are described below.
[0074] In some possible implementation manners, the first millimeter wave is generated and transmitted according to the LFMCW mode, and the second millimeter wave is generated and transmitted according to the PD mode.
[0075] In step S102, a first feedback based on the first millimeter wave will be obtained, and the first feedback is used to obtain the target distance. Here, the first feedback refers to the reflected wave generated by the reflection of the first millimeter wave on the tracking object, and the target distance refers to the distance between the controller (proximity fuse, aircraft) and the tracking object.
[0076] At the same time, in step 103, a second feedback based on the second millimeter wave is obtained, and the second feedback is used to obtain the target speed. Here, the second feedback refers to the reflected wave generated by the reflection of the second millimeter wave on the tracking object, and the target speed refers to the actual moving speed of the tracking object or the relative speed between the controller (proximity fuse, aircraft) and the tracking object.
[0077] After obtaining the target distance and target speed, it means that the tracking object has entered the coverage range of the controller (proximity fuse, aircraft). At this time, step S104 is executed. In this step, the first transmission channel and the second transmission channel are intermittently used to generate a mixed waveform to verify the target distance and target speed. The mixed waveform refers to the mixing of the first millimeter wave and the second millimeter wave in a mixing circuit. For the control of the mixing, it is carried out through time points. At this time, the synthesized waveform obtained based on the first millimeter wave and the second millimeter wave has characteristics significantly different from those of the first millimeter wave and the second millimeter wave, such as Figures 2 to 5 as shown
[0078] The rule for intermittently using the first transmission channel and the second transmission channel to generate a mixed waveform is: in the time series, the first millimeter wave is used to intermittently mix and encrypt the second millimeter wave, and the second millimeter wave is used to intermittently mix and encrypt the first millimeter wave.
[0079] It should be understood that for the control of time points, the random time point and the controlled time point methods can be used to achieve. The random time point refers to the start time point of the mixing control. By intervening in the controlled time point method, the advantage of this method is that the shape of the synthesized waveform can be known in advance, and there is no need to analyze the synthesized waveform.
[0080] By intervening in the random time point method, the advantage of this method is disorder, but it is necessary to analyze the synthesized waveform to obtain the corresponding synthesized waveform from the first feedback or the second feedback. At the same time, for the generation of random time points, parameters such as temperature, current, and voltage in the circuit can be used as true random number inputs to avoid the cracking of the generation method of random time points.
[0081] Finally, in step S105, a detonation signal is issued when the target distance meets the distance requirement. Please refer to Figure 6 , where the distance requirement is some pre-input parameters. For example, the distance requirement is set to 3m; or, the controller (proximity fuse, aircraft) has the ability to determine the target type and can select an appropriate target distance according to the target type.
[0082] In some possible implementation manners, the first millimeter wave and / or the second millimeter wave work in a pulse manner. The advantage of working in a pulse manner lies in the cracking difficulty and search speed. Because of the discontinuous working manner, it will cause the tracking target to spend more time searching for signals and analyzing signals in the time domain.
[0083] During the process of the controller (proximity fuse, aircraft) in the present application approaching the tracking target, it means that the probability of being deceived and interfered is lower, and the probability of hitting the target is increased.
[0084] In some possible implementation manners, in terms of the unit time length, there is at least one overlapping time length region between the time period of using the first millimeter wave to perform intermittent hybrid encryption on the second millimeter wave and the time period of using the second millimeter wave to perform intermittent hybrid encryption on the first millimeter wave.
[0085] Specifically, in this manner, three intermittent hybrid encryption methods (encrypting the first millimeter wave, encrypting the second millimeter wave, and encrypting the first millimeter wave and the second millimeter wave simultaneously) are used simultaneously to further reduce the probability of the signal being cracked.
[0086] In some possible implementation manners, the feedback received in the unit time length includes at least one echo that has been intermittently hybrid encrypted. This manner can ensure that the echoes generated by the millimeter waves (the first millimeter wave and the second millimeter wave) sent after intermittent hybrid encryption can be detected, so as to calculate the target speed and the target distance.
[0087] In some examples, after obtaining the target distance using the first feedback, please refer to Figure 7 , and it further includes the following steps:
[0088] S201, determine a position point on the tracking target that generates the first feedback, and denote it as the reference position point;
[0089] S202, taking the reference position point as a reference, delimit the exploration area, and at the same time select multiple reference position points within the exploration area;
[0090] S203, perform directional distance calibration and speed calibration on the reference position points;
[0091] S204, use the reference position points to construct a spatial movement model of the tracking target; and
[0092] S205, in the time series, correct the flight trajectory according to the movement trajectory of the spatial movement model;
[0093] Wherein, the spatial movement model includes at least two boundaries of the tracking target that have a symmetric relationship or a partial symmetric relationship;
[0094] The reference position points are divided into two groups. The first group of reference position points is located on the two boundaries of the spatial movement model, and the second group of reference position points is located in the middle area between the two boundaries of the spatial movement model.
[0095] Specifically, the content in steps S201 to S205 is to establish a tracking area on the tracking target, and through the analysis and determination of the tracking area, analyze and infer the relative distance from the tracking target. The advantage of this manner is that it can limit the exploration range of the millimeter wave and has an improvement in data sending, receiving, and anti-interference capabilities.
[0096] Furthermore, in the process of selecting multiple reference position points, the tracking target is scanned in the whole area intermittently and the positions of the reference position points are corrected according to the results of the whole area scanning. The purpose of correcting the reference position points is to correct the tracking area.
[0097] Intermittent full-area scanning of the target can also be misleading, because the uncertainty and disorder of this scanning method will cause the target to consume computing power to analyze and crack, and the interference measures generated by the cracking results will also be less targeted. Because in this application, the tracking area is mainly used to track the target.
[0098] In some examples, performing a full scan includes the following steps:
[0099] S301, selecting a pair of reference position points on two boundaries of the spatial movement model;
[0100] S302, establishing a scanning direction using a selected pair of reference position points; and
[0101] S303, performing a full-area scan of the tracking target in the scanning direction;
[0102] In one full-area scanning process, the number of pairs of reference position points selected is multiple times;
[0103] The angle between any two adjacent scanning directions in the time series is smaller than the required angle.
[0104] The contents of step S301 to step S303 are to calibrate and verify the analysis results of the tracking area to ensure the accuracy of the relative position with the tracking target. In this scanning method, the area of the global scan is guided by the scanning direction. The direction of each global scan may be different. Under the premise of directional disorder, the probability of the transmitted signal being intercepted is reduced, and each intercepted transmitted signal has certain differences in parameters.
[0105] In this way, an area associated with the tracking area can be selected on the tracking target to calibrate and verify the tracking area. While reducing the area of the processing area, it also reduces the probability of the transmitted signal being intercepted, which can improve the controller (proximity sound, aircraft) in this application's ability to strike the target.
[0106] The present application also provides a target recognition device, comprising:
[0107] A detection unit, configured to start a proximity detection mechanism in response to an acquired trigger signal, transmit a first millimeter wave using a first transmission channel, and transmit a second millimeter wave using a second transmission channel, wherein the first millimeter wave and the second millimeter wave have different wavelengths;

[0113] In the time series, the first millimeter wave is used to intermittently mix and encrypt the second millimeter wave, and the second millimeter wave is used to intermittently mix and encrypt the first millimeter wave.
[0114] Further, the first millimeter wave and / or the second millimeter wave operate in a pulse mode.
[0115] Further, in the unit time length, there is at least one overlapping time length region between the time period when the first millimeter wave is used to intermittently mix and encrypt the second millimeter wave and the time period when the second millimeter wave is used to intermittently mix and encrypt the first millimeter wave.
[0116] Further, the feedback received in the unit time length includes at least one echo that has been intermittently mixed and encrypted.
[0117] Further, it further includes:
[0118] The first selection unit is configured to determine a position point on the tracking target that generates the first feedback, denoted as the reference position point;
[0119] The second selection unit is configured to delimit an exploration area with the reference position point as a reference, and simultaneously select a plurality of reference position points within the exploration area;
[0120] The calibration unit is configured to perform directional distance calibration and speed calibration on the reference position points;
[0121] The model construction unit is configured to construct a spatial movement model of the tracking target using the reference position points; and
[0122] The correction unit is configured to correct the flight trajectory according to the movement trajectory of the spatial movement model in the time series;
[0123] Wherein, the spatial movement model includes at least two boundaries of the tracking target that have a symmetric relationship or a partial symmetric relationship;
[0124] The reference position points are divided into two groups. The first group of reference position points is located on the two boundaries of the spatial movement model, and the second group of reference position points is located in the middle area between the two boundaries of the spatial movement model.
[0125] Furthermore, during the process of selecting multiple reference position points, the tracking target is intermittently scanned globally, and the positions of the reference position points are corrected according to the global scanning results.
[0126] Furthermore, it further includes:
[0127] A third selection unit for selecting a pair of reference position points on the two boundaries of the spatial movement model;
[0128] A direction unit for establishing a scanning direction using the selected pair of reference position points; and

[0130] Wherein, during one global scanning process, the number of pairs of reference position points selected is multiple;
[0131] The included angle between any two adjacent established scanning directions in the time series is less than the required angle.
