Abstract
Description
Technical Field
[0001] This invention relates to the field of radar signal processing technology, and in particular to a method and apparatus for phase compensation of the receiving channel of an antenna subarray. Background Technology
[0002] A large antenna array is physically and circuitically divided into several smaller modular combinations, each called a subarray. Each antenna subarray corresponds to an independent signal reception and processing link, i.e., a receiving channel. Each channel can independently receive, amplify, filter, and convert radio frequency signals from a specific direction into digital intermediate frequency or baseband signals. By precisely controlling the phase of the received signals from each channel and synthesizing them in the digital domain, the system achieves functions such as beamforming, beam scanning, and interference suppression, ultimately greatly improving the antenna's directional receiving gain and spatial resolution.
[0003] In related technologies, to find the compensation phase that achieves the best synthesis effect, it is necessary to consider the overall synthesis effect of the antenna under different orientations (i.e., different azimuth angles). Traditional methods require performing a complete test procedure for each compensation phase value to be tested. Therefore, when there are many phase values to be tested and the step size is small, this method will generate a huge amount of repetitive work, resulting in low efficiency.
[0004] Therefore, there is an urgent need for a phase compensation method and device for the receiving channel of an antenna subarray to solve the above-mentioned technical problems. Summary of the Invention

By automating batch processing, it completes channel synthesis calculations for all possible phase values within a preset range in one go, completely changing the inefficient traditional manual phase-by-phase trial and repeated "synthesis-analysis-plotting" mode. This allows for setting finer compensation steps to find better solutions, while greatly reducing manual operation and time consumption.

Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0014] Please refer to Figure 1 The present invention provides a phase compensation method for an antenna subarray receiving channel, the method comprising: Step 100: Convert the raw time-domain signal data obtained by directional scanning of the antenna subarray into channel spectra with directional angle labels; Step 102: Perform channel synthesis calculation on the channel spectrum within the preset compensation phase range to obtain the channel synthesis dataset corresponding to all compensation phase values; Step 104: Dynamically process the channel synthesis dataset to obtain a channel synthesis pattern that varies with the compensation phase.
[0015] In this embodiment of the invention, the efficiency and accuracy of phase compensation for the receiving channel of the antenna subarray are significantly improved through an automated process. Batch automated processing completes the channel synthesis calculation for all possible phase values within a preset range in one go, completely changing the inefficient traditional manual phase-by-phase trial and repeated "synthesis-analysis-plotting" mode. This allows for setting finer compensation steps to find better solutions, while greatly reducing manual operation and time consumption. By dragging the slider, the entire process of the synthesized radiation pattern and key indicators changing with the compensation phase can be continuously and in real time observed. This strong visual correlation makes the determination of the optimal compensation phase intuitive and convenient, greatly enhancing the understanding of the evolution law of the synthesis effect and facilitating subsequent backtracking and analysis of the compensation process.
[0016] The following description Figure 1 The execution method of each step is shown.
[0017] First, for step 100, the original time-domain signal data obtained by directional scanning of the antenna subarray is converted into channel spectra with directional angle labels.
[0018] In this embodiment of the invention, the channel spectrum is obtained as follows: Protocol parsing is performed on the frame header of the original time-domain signal data to obtain a fixed number of sampling points characterizing the length of each frame; directional angle parsing is performed on each frame of the original time-domain signal data to obtain the directional angle corresponding to each frame; protocol parsing is performed on each frame of data according to the fixed number of sampling points to obtain the time-domain signal sequence of all channels to be synthesized corresponding to each frame; frequency domain transformation is performed on the time-domain signal sequence to obtain the complex spectrum corresponding to the time-domain signal sequence; the directional angle and complex spectrum corresponding to the same frame of data are correlated to obtain the channel spectrum of all frames of data with directional angle labels.
[0019] Specifically, assuming the radar antenna continuously collects and receives data... M A pulse train echo signal, with each pulse having a sampling point of . N The signal is represented as .
[0020] The data file is parsed by analyzing the data length, azimuth / elevation angles, and frame data, calculating the spectrum, and recording the spectrum corresponding to the azimuth / elevation angles of all frames.
[0021] Parse the data length. Based on the data file format protocol, parse the frame header and extract the number of sampling points for each pulse in the data file. N Since the number of sampling points for the collected data remains constant, subsequent parsing and processing of each frame of data should be based on this number of sampling points.
[0022] Analyze the azimuth / elevation angle of the current frame. Since judging the effect of receiver channel synthesis requires observing and comparing the radiation patterns before and after synthesis, and the collected data is obtained from directional scanning, it is necessary to correlate the data of each frame with the azimuth / elevation angle. Therefore, it is necessary to analyze the azimuth / elevation angle of the current frame. i Frame azimuth / pitch angle .
[0023] Parse the current frame data. Parse the data according to the arrangement of different channels in the file data format protocol. i Frame number l Data from one channel to be synthesized .
[0024] Calculate the spectrum. Find the current [number] [element / section]. i Frame number l Signal data of each channel to be synthesized The spectrum is obtained .
[0025] Obtain the spectrum corresponding to the azimuth / elevation angles of all frames. (The remaining text appears to be incomplete and requires further context.) i Frame number l The signal spectrum of each channel to be synthesized With the i The azimuth / elevation angle correspondence of the frame is as follows: .
[0026] Then, for step 102, channel synthesis calculation is performed on the channel spectrum within the preset compensation phase range to obtain the channel synthesis dataset corresponding to all compensation phase values.
[0027] In this embodiment of the invention, the channel synthesis dataset is obtained in the following manner: S21. Extract the frequency of the channel spectrum of all frame data, determine the center frequency of all channels to be synthesized in each frame data, and the reference spectrum value with direction angle label corresponding to the center frequency. S22. Generate a sequence of compensated phase values for each frame of data within the compensated phase range according to a preset step. S23. Read the compensation phase value sequence sequentially to obtain the current compensation phase value used in this calculation cycle; S24. Perform phase-shifting processing on the reference spectrum value of the current channel according to the current compensation phase value to obtain the phase-shifted spectrum value; S25. The phase-shifted spectrum value and the spectrum value corresponding to the center frequency of the remaining channel to be synthesized in the same frame of data are merged sequentially to obtain the channel synthesis direction under the current compensation phase value. S26. Update the loop count and repeat steps S23-S26 until each compensation phase value in the compensation phase value sequence has been read once, and generate a channel synthesis dataset containing the synthesis results corresponding to all possible compensation phases according to all channel synthesis directions.
[0028] Specifically, by extracting the spectrum corresponding to the center frequency, obtaining the compensation phase, phase shifting the synthesized channel, synthesizing the channel, and recording the current phase compensation value and synthesis effect, the channel to be synthesized is synthesized under the specified phase compensation.
[0029] Taking the synthesis of two receiving channels as an example, the spectrum corresponding to the center frequency is extracted. Since the transmitted signal is a point-frequency signal, it has the largest signal amplitude and the highest signal-to-noise ratio at the center frequency, making it easier to observe the channel synthesis effect. The spectrum corresponding to the center frequency is then extracted. i Frame number l The center frequency of each channel to be synthesized The correspondence between the spectrum and its azimuth / elevation angle: .
[0030] Obtain the current compensation phase. Based on the set compensation phase range (since the phase is periodic from 0° to 360°, it is usually set to 0°~360° to observe the channel synthesis results of all phase compensations), read the current compensation phase applied during channel synthesis. k Each compensation phase value .
[0031] Phase shift of the synthesized channel. Assume the first... l If the first channel is the channel to be synthesized, then for the second channel... l Phase shift of each channel ,have to: .
[0032] Channel synthesis. Suppose we need to synthesize the first channel. p The receiving channel and the first l If there are multiple receiving channels, the resulting composite pattern corresponding to the current phase compensation value is: .
[0033] Obtain the composite effect of all phase-compensated channels. Iterate through all orientation angles and phase values using the above process until the complete dataset is obtained. After completing all phase compensation and channel compositing, the result is the [number of channels]. k Phase compensation value Correspondence between the composite effect pattern and the pattern: ,in This indicates the calculation of the amplitude of the corresponding complex spectrum.
[0034] like Figure 2 As shown, the blue line represents the composite effect. Observing the changes in the left and right sidelobes of the two-channel composite, it can be seen that the composite pattern exhibits a cyclical change between the zero-depth state with completely opposite phases as the compensation phase changes, transitioning between the optimal compensation state for successful composite: In the zero-depth state, the sidelobe wrapped by the main lobe is considered one side of the zero-depth, and the sidelobe on the other side is considered the other side of the zero-depth. As the compensation phase changes, the sidelobe wrapped in the main lobe gradually becomes visible, separates from the main lobe, and gradually rises; simultaneously, the sidelobe on the other side of the zero-depth gradually decreases. When the two sidelobes are at the same height, the corresponding compensation phase is often the optimal compensation phase. As the compensation phase continues to change, the sidelobe that was wrapped in the main lobe in the previous zero-depth state gradually rises to become one side of the new zero-depth state, while the sidelobe that was one side of the zero-depth in the previous zero-depth state gradually decreases and is wrapped by the main lobe. This process repeats.
[0035] Figure 3 A comparison of metrics between the zero-depth state and the optimal compensation state for successful synthesis is presented. It can be seen that the optimal compensation state has a more centered synthesis orientation and a higher synthesis amplitude gain.
[0036] For step 104, the channel synthesis dataset is dynamically processed to obtain a channel synthesis pattern that varies with the compensation phase.
[0037] In this embodiment of the invention, the channel synthesis pattern is obtained as follows: performance indicators are extracted from the channel synthesis patterns corresponding to all compensated phase values in the channel synthesis dataset to obtain and display the quantization synthesis effect of the indicators included in each compensated phase value; a slider corresponding to the indicator range is generated on the display interface according to the quantization synthesis effect, and phase value mapping and parsing processing is performed according to the position of the slider after the user terminal moves to obtain the precise phase value that the current user terminal needs to observe; the channel synthesis dataset is searched and queried according to the precise phase value to obtain the real-time channel synthesis pattern display.
[0038] Specifically, the channel synthesis direction display map in this embodiment is essentially a replay of the calculation results. It achieves dynamic display of the channel synthesis effect as the phase compensation value changes by displaying the channel synthesis direction map of the initial phase compensation value, calculating and displaying the channel synthesis effect index of the initial phase compensation value, triggering the phase compensation value change by moving the interface slider, displaying the synthesis direction map corresponding to the current phase compensation value, and calculating and displaying the current channel synthesis effect index.
[0039] Displays the channel synthesized pattern of the initial phase compensation value. To achieve a user-friendly interface, the channel synthesized result of the first phase compensation value is displayed immediately after channel synthesis is completed. .
[0040] Calculate and display the channel synthesis effect metrics for the initial phase compensation value. The calculated channel synthesis effect metrics include the synthesized amplitude, synthesized antenna pointing, main lobe 3dB bandwidth, and main lobe 6dB bandwidth.
[0041] Wait for the slider to move. When the slider in the interface moves, the process of displaying the composite effect of the current compensation phase value is triggered.
[0042] Read the current phase compensation value. After the slider is moved, find the nearest phase compensation value on the scale based on the current slider position.
[0043] Displays the composite pattern corresponding to the current phase compensation value. Based on the currently found phase compensation value, it searches for and displays the composite pattern of the current phase compensation value among all phase compensation values and composite results.
[0044] Calculate and display the current channel synthesis performance metrics. Based on the synthesis pattern of the current phase compensation values, calculate and display the channel synthesis performance metrics.
[0045] like Figure 4 As shown, as the slider moves, the interface will dynamically display the changes in the synthesized radiation pattern as the compensation phase changes.

The processing module 504 is used to dynamically process the channel synthesis dataset to obtain a channel synthesis pattern that varies with the compensation phase.
[0047] In this embodiment of the invention, converting the raw time-domain signal data acquired by directional scanning into a channel spectrum with directional angle labels includes: The frame header of the original time-domain signal data is processed by protocol parsing to obtain a fixed number of sampling points used to characterize the length of each frame of data; Each frame of the original time-domain signal data is analyzed for the orientation angle to obtain the orientation angle corresponding to each frame of data. Based on the fixed number of sampling points, each frame of data is parsed according to the protocol to obtain the time-domain signal sequence of all channels to be synthesized corresponding to each frame of data; Perform a frequency domain transformation on the time-domain signal sequence to obtain the complex spectrum corresponding to the time-domain signal sequence; By associating the orientation angle and complex spectrum corresponding to the same frame of data, the channel spectrum of all frames of data with orientation angle labels is obtained.

The phase-shifted spectrum value and the spectrum value corresponding to the center frequency of the remaining channel to be synthesized in the same frame of data are merged sequentially to obtain the channel synthesis direction under the current compensation phase value. S26. Update the loop count and repeat steps S23-S26 until each compensation phase value in the compensation phase value sequence has been read once, and generate a channel synthesis dataset containing the synthesis results corresponding to all possible compensation phases according to all channel synthesis directions.
