All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] In the description of the embodiments of the present invention, "multiple" means at least two.
[0022] Example 1: During target maneuvering, due to the large range of the target maneuver, there may be a significant deviation between the predicted target position and the actual target position, resulting in ineffective coverage by the tracking beam and causing target tracking loss or dropping. Therefore, this example provides a method to improve the azimuth range of near-field maneuvering target tracking coverage, such as... Figure 1 As shown, the specific steps include the following: S1 extends the coverage of the original beam by increasing the number of beams at both ends of the beam where the predicted target location is located using a digital phased array.
[0023] S2, tracking and covering maneuvering targets based on the extended transmit and receive beams, wherein the transmit and / or receive beams include at least a left beam, a middle beam, and a right beam; wherein the transmit and / or receive beams are formed by radio frequency signals.
[0024] Optionally, the above-mentioned tracking and coverage of maneuvering targets based on the extended transmit and receive beams is specifically as follows: S21, acquire the trajectory data of the maneuvering target, and calculate the tracking beam that needs to be scheduled based on the trajectory data.
[0025] S22, based on track data and tracking beam, predicts the beam position of the maneuvering target in the next fixed cycle through track processing.
[0026] S23, the beam position is obtained by solving to obtain a new tracking beam that needs to be scheduled until the maneuvering target leaves the preset airspace.
[0027] Optionally, the above implementation method is implemented through an implementation system, which includes: The main control module is used for data transmission, beam scheduling control, and command and data interaction with external display control terminals.
[0028] The main control module includes an FPGA and a CPU. The FPGA uses a double-buffered design to complete data transfer and transmission, while the CPU mainly performs beam scheduling control and command and data interaction with the external display control terminal.
[0029] The aforementioned implementation system also includes: The beam control module is used for encoding, digital signal transfer and transmission, as well as receiving control commands from the main control module and performing beam position scheduling, parameter data parsing and calculation based on the control commands.
[0030] The beam control module comprises an FPGA and a CPU. The FPGA primarily handles encoding, digital signal transfer, and transmission. Specifically, the FPGA receives control commands, leverages its parallel processing capabilities to complete multi-channel synchronous encoding, and integrates a high-speed cache module to store digital signals. A double-buffered design enables seamless switching and transmission of digital signals. The CPU primarily receives control commands from the main control module, performing beam position scheduling, parameter data parsing, and calculation. The CPU receives control commands from the main control module via a standard Ethernet interface and employs a bidirectional verification mechanism to ensure the integrity and accuracy of the received commands. A breakpoint mechanism prioritizes critical instructions, reducing latency caused by context switching. Upon receiving beam position scheduling commands from the main control module, the CPU sequentially schedules beam positions according to a preset scheduling method. In multi-target tracking scenarios, a priority queue model is used to dynamically schedule and allocate beams, responding to beam position scheduling for the beam containing the target being tracked. The CPU also undertakes the tasks of parsing and calculating beam parameter data, including parsing and calculating control parameters (amplitude, phase, and power, etc.), and sending the generated configuration data to the FPGA for multi-channel real-time processing.
[0031] The aforementioned implementation system also includes: The beamforming module is used for transferring and transmitting parameter data, as well as for processing beam data synthesis.
[0032] The beamforming module includes an FPGA, primarily responsible for parameter data transfer and transmission, beam data synthesis processing, etc. The FPGA integrates multiple high-speed cache modules to receive parameter configuration data from the source, including initial settings for amplitude, phase, and power. A double-buffered design is used to transfer and transmit the parameter configuration data. Based on the beamforming algorithm, the weighted values of each antenna array are calculated and synthesized. The FPGA's global clock network ensures that the data is aligned before transmission, precisely controlling the amplitude, phase, and power of each antenna array signal to achieve directional beam transmission. The module receives digital baseband signals from each T / R component, uses the FPGA's global clock network to perform timing alignment of the received digital baseband signals, and performs weighted calculations and synthesis processing on the signals of each antenna array according to the beamforming algorithm to form the synthesized beam data.
[0033] The aforementioned implementation system also includes: The T / R module is used to receive the radio frequency signal from the antenna vibrator, limit and amplify the radio frequency signal, demodulate it into a digital baseband signal and send it to the beamforming module for processing. It is also used to receive data sent by the beamforming module, and after parsing, modulation and amplification, output radio frequency signals to the antenna vibrator for transmission.
[0034] The T / R module includes a transmit / receive channel, a transmit / receive switch, and a digital processing module. After receiving the radio frequency signal from the antenna vibrator, the receive channel uses the digital processing module to limit, amplify, and demodulate it into a digital baseband signal, which is then sent to the beamforming module for processing. After receiving and parsing the data from the beamforming module, the digital signal is converted into an analog waveform through a DA converter, modulated, amplified, and then the radio frequency signal is output to the antenna vibrator for transmission through the transmit channel.
[0035] The aforementioned implementation system also includes: The data processing module receives data sent by the beamforming module and performs decoding processing; it also receives the first control command from the main control module and processes and filters the decoded data obtained from the decoding process according to the first control command to form point data.
[0036] The data processing module includes an FPGA and a CPU. The FPGA mainly receives and processes the synthesized beam data, performs pulse frame detection and matching, pulse width detection, pulse recording, and encapsulates it into a decoded data message, which is then sent to the CPU through a shared bus interface. The CPU mainly receives control commands from the main control module, processes and filters the decoded data, receives the decoded data message, extracts pulse feature data, performs data parsing, filters out false points, and encapsulates it into a point trace data message containing information such as distance and azimuth.
[0037] The aforementioned implementation system also includes: The track processing module is used for data transfer and transmission, as well as receiving the second control command from the main control module, and processing and filtering the point data according to the second control command to form track data.
[0038] The trajectory processing module includes FPGA and CPU components. The FPGA integrates a data cache module, which is mainly responsible for data transfer and transmission. The CPU component mainly receives control commands from the main control module, processes and filters point data, receives point data messages, extracts target distance and orientation features, performs target point correlation, filters out some abnormal points, merges them to form convergent points, performs trajectory filtering and smoothing, forms trajectory data, and reports it. In multi-target tracking scenarios, it initiates near-area tracking requests for near-area targets according to predetermined rules.
[0039] Specifically, when the secondary radar performs normal target surveillance and detection within its monitoring range, if a target is detected in the nearby area and its trajectory is stable, a periodic near-field target tracking and surveillance mechanism for that target is triggered. Figure 2 As shown, under normal target surveillance conditions, the track processing module reports target track information from the nearby area to the main control module. According to predetermined rules, it initiates a near-field target tracking request for nearby targets. When the main control module receives the near-field target tracking request, it parses the target's tracking request information, extracting key parameters such as the target's code, position, speed, and heading. It then performs a comprehensive evaluation based on the current operating status of the equipment (available beam resources, etc.). Subsequently, the main control module, combining the heading and other parameters from the current inertial navigation information, calculates the tracking beam resources for this target tracking mission using a preset algorithm.
[0040] During the next beam scan, target tracking beam scheduling control is executed first. The main control module sends a beam position control command to the beam control module. After receiving the beam position control command, the beam control module uses a priority queue model to dynamically schedule and allocate beams, responding to the beam position scheduling of the beam where the tracking target is located. The beam control module parses and calculates the parameter data of the beam where the tracking target is located, including parsing and calculating control parameters (amplitude, phase, power, etc.), and sends the generated configuration data down for multi-channel real-time processing, synchronously performing encoding control according to the preset tracking mode. Then, the configuration data is sent to the beam combining module for weighted processing, used to control the amplitude, phase, and power of the signals emitted by the corresponding antenna elements of each T / R component. After weighted processing, it is sent to the T / R component. The T / R component receives the data from the beam combining module, parses it, modulates and amplifies it, and outputs the radio frequency signal to the antenna element to realize the directional transmission of the tracking beam. At the same time, the status information of the current tracking beam is transmitted in real time to the data processing module and track processing, providing data support for subsequent target parameter updates and trajectory prediction.
[0041] The T / R module receives the target's response signal from each antenna element, demodulates the received response signal into a digital baseband signal, and sends it to the beamforming module for processing. The beamforming module performs timing alignment on the received digital baseband signal, and according to the beamforming algorithm, performs weighted calculations and synthesis on the signal from each antenna element to form synthesized beam data. This beam data is then sent to the data processing module for parsing. The data processing module performs pulse frame detection and matching, pulse width detection, and pulse recording on the signal waveform. It then encapsulates the pulse data into a raw decoded data message, processes and filters the decoded data, extracts pulse feature data, performs data parsing, filters out false points, and encapsulates it into a point data message containing information such as range and azimuth. This point data message is then sent to the track processing module. The track processing module extracts the target's range and azimuth feature information from the received point data message to perform target tracking. Information is relevant; some abnormal points are filtered out. Based on the nearest neighbor association algorithm, the data is fused to form convergence points, and then trajectory filtering and smoothing are performed to form track data, which is then reported. Track processing integrates dynamic parameters such as target position, velocity, and heading angle from historical trajectories, combined with the equipment's scanning cycle, and uses a target trajectory prediction algorithm to perform high-precision calculations of the possible positions of near-field targets in the next fixed cycle, predicting the location information of the target being tracked, and simultaneously sending it to the main control module. The main control module, combined with the heading and other parameters of the current inertial navigation information, calculates the tracking beam resources for the target tracking task according to a preset algorithm, and then executes target tracking beam scheduling control again. If the target leaves the vicinity of the secondary radar, the near-field tracking application for that target is revoked. In the above process, the calculation, prediction, and beam control of received signals are all relatively mature technologies that can be implemented using existing methods, and will not be elaborated further here.
[0042] In this embodiment, when the near-field target has a large maneuvering range, there may be a deviation between the predicted target position and the actual target position. In this case, the tracking beam cannot effectively cover the maneuvering target, resulting in target data loss or dropped data. Therefore, the following is addressed: Taking advantage of the rapid beamforming capability of digital phased arrays, at the two ends of the beam where the predicted target location is located, such as... Figure 3 As shown, the number of beams is increased, expanding the coverage of the original single beam. During transmission, the transmit beam is expanded to cover the left transmit beam, the transmit beam, and the transmit right beam; during reception, the receive beam is expanded to cover the left receive beam, the receive beam, and the receive right beam. See [link to documentation]. Figure 3 This increases the effective range of beam coverage, increasing the azimuth coverage of a single beam to three times the original azimuth coverage, with the transmitting and receiving beams executed sequentially.

The tracking coverage unit is used to track and cover maneuvering targets based on extended transmit and receive beams, wherein the transmit and / or receive beams include at least a left beam, a middle beam, and a right beam.
[0044] The aforementioned tracking and coverage of maneuvering targets based on the extended transmit and receive beams is achieved through the following methods: Acquire the trajectory data of the maneuvering target, and calculate the tracking beam that needs to be scheduled based on the trajectory data; Based on the trajectory data and tracking beam, the beam position of the maneuvering target in the next fixed cycle is predicted through trajectory processing. The beam position is calculated to obtain a new tracking beam that needs to be scheduled until the maneuvering target leaves the preset airspace.
