[0028] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the disclosure or its application or uses. Figures 1-13 The present disclosure provides a solution for antenna array control of digital array radar.

[0029] Embodiment 1 Figure 1 is a flowchart of an antenna array control method for digital array radar provided by an exemplary embodiment of the present disclosure. The antenna array control method is executed on an array control terminal, which is communicatively connected with a user terminal. Referring to Figure 2 , an array control software can be run on the array control terminal, which can be divided into three functional modules, i.e., library file management, user terminal command analysis, and array control parameter generation (i.e., the "array control instruction" to be mentioned below).

[0030] Specifically, referring to Figure 1 , the antenna array control method comprises: S11, updating a library file based on the user terminal.

[0031] S12, in response to receiving task information sent by the user terminal, determining array control information based on the task information.

[0032] S13, determining an array control instruction based on the array control information and the library file associated with the array control information.

[0033] S14, issuing the array control instruction to a digital array unit of the digital array radar.

[0034] The library file is a parameter file predefined by a user and related to the antenna array surface control. Specifically, the user (e.g., an engineer or an operator) can configure the user terminal according to a task type, thereby abstracting fixedly used parameters related to the antenna array surface control into a library file and storing the library file in the user terminal. Then, the array control terminal as an execution subject can update the library file on the array control terminal side based on a manner of communication connection with the user terminal. Specific implementation details will be described below, and thus are not described here.

[0035] It should be noted that the type of the library file is not limited in the present disclosure. For example, the library file can include, but is not limited to, an antenna array definition library, a transmission coding library, and a beam shape library.

[0036] It should be noted that the specific form of the array control terminal is not limited in the present disclosure. For example, the array control terminal can be a central control console, which can communicate with a digital array radar, thereby transmitting a control instruction to an antenna array of the digital array radar.

[0037] In addition, it should be noted that the manner of communication connection between the array control terminal and the user terminal is not limited in the present disclosure. For example, the communication can be performed in a wired or wireless manner. The wireless manner can include, but is not limited to, WIFI, a mobile communication network, and the like.

[0038] The task information can include at least a library number corresponding to the library file, a time parameter, a phase parameter, a baseband wave parameter, and the like. Specific details will be described in the embodiments below, and thus are not described here.

[0039] The array control information can be pulse repetition interval (PRI) level control information. The array control instruction can be a control parameter corresponding to each PRI period.

[0040] Optionally, the array control instruction can be issued in a time sequence, and specific details will be described below.

[0041] In summary, the antenna array surface control method for a digital array radar provided by the embodiments of the present disclosure can achieve the following effects. On the one hand, the array control terminal as an execution subject can obtain task information (data stream driving) and corresponding library files based on communication with a user terminal, thereby achieving array control effects for different tasks, i.e., achieving parameterized control. For example, when a task type is changed, the digital array module (DAM) can be expanded and multiplexed, and the antenna array surface working mode can be flexibly switched to match different tasks. On the other hand, the array control terminal as an execution subject adopts the manner of importing a library file, and the array control method of the embodiments of the present disclosure can quickly match a reconstructed antenna array after the antenna array is changed, thereby shortening the development time of a control program.

[0042] Embodiment 2 In the above embodiment 1, as an optional implementation, the task information comprises at least one first parameter of a first time level arranged in time sequence.

[0043] Each of the first parameters of the at least one first time level comprises second parameters of a plurality of second time levels arranged in time sequence, and a sum of the plurality of second times is less than or equal to the first time. Each of the second parameters of the second time level comprises at least a phase parameter matching a task type, a baseband wave parameter, a library number of a library file, and a digital array unit identifier to be controlled within the second time.

[0044] As an optional example, the first time is a coherent processing interval (CPI) time, and the second time is a pulse repetition interval (PRI) time. Here, the first time and the second time are the aforementioned time parameters.

[0045] As an optional example, the task type comprises at least any one or any several of scanning, tracking search, tracking, confirmation, identification, self-check, and calibration.

[0046] As an optional example, the phase parameter can comprise a beam pointing direction, and the baseband wave parameter can comprise a waveform, a pulse width, a duty cycle, a transmission frequency, etc.

[0047] As an optional example, the library number can comprise two indexes, one of which represents a library type, and the other of which represents a serial number of the library file of the type. For example, A1 represents the first of the A category library files.

[0048] As an optional example, the identifier of the digital array unit (DAM) to be controlled can be represented in various ways. For example, the physical layout information of the digital array unit can be used as the identifier. Specifically, DAM-1-12 can represent the DAM in the first row and the twelfth column of the antenna array surface.

[0049] In the above embodiments 1 and 2, as an optional implementation, the step S12 of “determining array surface control information based on the task information in response to receiving the task information sent by the user terminal” can be implemented in the following manner: analyzing the task information based on a preset analysis rule to obtain the array surface control information. The array surface control information is the second parameter of the second time level.

[0050] As an optional example, with reference to Figure 3 , the analyzing the task information based on the preset analysis rule to obtain the array surface control information can be implemented in the following manner: Firstly, according to time sequence, each first time level first parameter in the at least one first time level first parameter is decomposed into independent multiple second time level second parameters; Secondly, the independent multiple second time level second parameters are stored.

[0051] Referring to Figure 2 and Figure 3 , the array control terminal as an execution subject runs the array control software, wherein the "user terminal command analysis" module in the array control software is responsible for performing the above analysis process.

[0052] Specifically, referring to Figure 3 , after receiving the task information, the "user terminal command analysis" module performs the following steps: Step 1) The first time identifies the number of first time level first parameters (i.e. CPI level data packets) contained in the task information, denoted as N, which is a positive integer.

[0053] Step 2) According to the time length occupied by the CPI level data packet, the CPI data packet in the task information is split according to time sequence.

[0054] Step 3) The CPI level data packet obtained in step 2) is further split according to time sequence and in the form of the second time level second parameter (i.e. PRI level data packet).

[0055] Step 4) The PRI level data packet obtained in step 3) is stored.

[0056] Step 5) The number of current CPI data packets is counted, denoted as M, which is a positive integer and the initial value is 0.

[0057] Step 6) It is judged whether the current decomposed CPI data packet is the last one in the received task information, if yes, iteration steps 2)~5) are performed; if not, the iteration is ended. The judgment is based on the comparison of the values of M and N, when M=N, it is confirmed that the current decomposed CPI data packet is the last one in the received task information, and the iteration is ended.

[0058] Based on the above embodiments 1 and 2, as an optional implementation, referring to Figure 4 , the step S13 "determining the array control instruction based on the array control information and the library file associated with the array control information" can include the following steps: S131, based on the phase parameter in each second time level second parameter matching the task type, the library number of the library file associated with the phase parameter, and the digital array unit identifier to be controlled, determining the beam synthesis control command of each digital array unit to be controlled in each second time.

[0059] As an optional example, referring to Figure 5 , step S131 can include the following steps: S1311, calling the pre-stored library file associated with the phase parameter by using the library number of the library file associated with the phase parameter.

[0060] Wherein, the library file index table associated with the library number can be established synchronously when step S11 "updating the library file based on the user terminal" is performed.

[0061] S1312, generating the beam synthesis control command of each to-be-controlled digital array unit in each of the second time based on the phase parameter, the library file associated with the phase parameter, and the identification of the digital array unit to be controlled, by using a preset beam synthesis calculation rule.

[0062] Wherein, it should be noted that the preset beam synthesis calculation rule can include multiple types. For example, it can include but is not limited to multi-phase filter bank channelization method, frequency domain beam forming algorithm, adaptive beam forming algorithm, FFT / DFT-based algorithm, deep learning driven method.

[0063] Wherein, the beam synthesis control command can include the related control parameters of the channel matching of the digital array unit (DAM), the filter coefficient, the array surface channel control, and the timing control.

[0064] S132, storing the beam synthesis control command of each to-be-controlled digital array unit in each of the second time.

[0065] Wherein, the beam synthesis control command can be stored in the storage unit (for example, hard disk) of the array surface control terminal itself; it can also be stored in the storage device (for example, data storage server) capable of being communicatively connected with the array surface control terminal.

[0066] S133, determining the chip control generation control command of each to-be-controlled digital array unit in each of the second time based on the baseband wave parameter matching the task type in each of the second parameter, the library number of the library file associated with the baseband wave parameter, and the identification of the digital array unit to be controlled.

[0067] As an optional example, referring to Figure 6 , step S133 can include the following steps: S1331, calling the pre-stored library file associated with the baseband wave parameter by using the library number of the library file associated with the baseband wave parameter; S1332, based on the baseband wave parameter, the library file associated with the baseband wave parameter, and the digital array unit identifier to be regulated, generating a chip control generation calculation rule, generating a chip control generation control command of each digital array unit to be regulated in each second time.

[0068] It should be noted that the preset chip control generation calculation rule can include multiple types. For example, it can include but is not limited to adaptive waveform optimization algorithm, neural network optimization chip parameter, space-time adaptive processing (STAP) algorithm, etc.

[0069] Among them, the chip control generation control command can include the transmission baseband waveform of the digital array unit (DAM), the related parameters of the direct digital frequency synthesis (DDS) and the digital down conversion (DDC).

[0070] S134, store the chip control generation control command of each digital array unit to be regulated in each second time.

[0071] Among them, the chip control generation control command can be stored in the storage unit (for example, hard disk) of the array control terminal itself; It can also be stored in a storage device (for example, a data storage server) that can be connected in communication with the array control terminal.

[0072] Based on the above embodiments 1 and 2, as an optional implementation, referring to Figure 7 , the step S11 "based on the user terminal update library file" can include the following steps: S111, send the first state information to the user terminal.

[0073] Among them, the first state information includes the type and quantity of the currently stored library file.

[0074] Specifically, referring to Figure 2 , 8 The "array control software" running on the array control terminal uses the "library file management" module to perform the "read library file state" operation on itself, and whether it can be sent to the user terminal through "send state (that is, the above-mentioned "first state information")".

[0075] S112, in response to receiving the incremental library file returned by the user terminal, storing the incremental library file, and constructing a library file index table associated with the library number.

[0076] Here, referring to Figure 8The user terminal can push the "incremental library file" to the "library file management" module of the array control terminal by means of "sending a library file". The "library file management" module can store the "incremental library file" by means of "library file transfer" and synchronously execute the operations of "filling in a library file index table and updating a library file state".

[0077] S113, sending second state information to the user terminal; wherein the second state information comprises the type and quantity of the updated stored library file.

[0078] Here, the second state information is determined when the library file state is updated in step S112.

[0079] In addition, optionally, the array control terminal can initialize the input and output interface and the memory at each power-on start, and then execute the above steps S111-S113. On the basis of the above embodiment, as an optional implementation manner, the step S14 "issuing the array control instruction to the digital array unit of the digital array radar" can be implemented by the following manner: First, according to the time sequence, the beam synthesis control command and / or the chip control generation control command to be executed in each second time for each to-be-controlled digital array unit are determined in sequence; then, according to the time sequence, the beam synthesis control command and / or the chip control generation control command to be executed in each second time are sent to the corresponding each to-be-controlled digital array unit.

[0080] In this way, the technical effect that the array can issue the "array control instruction" calculated in the foregoing steps to the corresponding each digital array unit (DAM) in sequence according to the time sequence information can be achieved.

[0081] On the basis of the above embodiment, as an optional implementation manner, after the step S12 is executed, the antenna array control method can further comprise: Serving the third state information to the user terminal.

[0082] Wherein, the third state information comprises a state parameter representing the receiving state of the task information and the analysis state of the task information.

[0083] In this way, the user can know the task execution state in time through the user terminal, so as to facilitate the subsequent task flow operation.

[0084] As described above, by using the antenna array control method for digital array radar provided by the embodiments of the present disclosure, on one hand, the array control terminal as an execution subject can obtain task information and corresponding library files (data stream driving) based on communication with the user terminal, so as to realize parameterized control for different array control tasks, and then when the task type is changed, the expansion and multiplexing of the digital array module (DAM) and the flexible switching of the antenna array working mode can be matched. The antenna array working mode can include but is not limited to single-transmit single-receive mode (SISO), single-transmit multiple-receive mode (MISO) and multiple-transmit multiple-receive mode (MIMO).

[0085] On the other hand, the array control terminal as an execution subject adopts the way of importing library files, and when the antenna array is changed, the array control method of the embodiments of the present disclosure only needs to adaptively update and call different library files to meet the needs after the change, without adjusting the basic business logic framework, so that the reconstructed antenna array can be quickly matched, and then it also means that the time for technicians to develop control programs is correspondingly shortened.
