[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Summary of the application Beam pointing accuracy refers to the pointing deviation between the ideal beam and the actual beam. With the development of radar technology and the need for target detection and control, phased array antennas have become the mainstream of radar antenna development. The use of controllable phase shifters is the key to realizing the superior performance of phased array antennas. Due to design deficiencies and amplitude and phase errors between phased array elements introduced during production, beam pointing errors of phased array antennas are caused.
[0023] Depending on the functional frequency and manufacturing complexity of different antennas, the linearity error varies considerably. Traditional beam pointing testing methods involve searching for actual pointing data within a certain range around the theoretical pointing position. The steps are as follows: First, a turntable or robotic arm is controlled to rotate the antenna to the theoretical pointing position within a certain angular range. Amplitude and phase data of this range are then collected via mechanical or electronic scanning. Based on the collected amplitude and phase data, an algorithm calculates the antenna pointing error value. If the pointing error value is not found within the current test range, the test range needs to be expanded until the pointing error data is found.
[0024] However, this method requires stopping and starting repeatedly to test and calibrate the pointing accuracy one by one, which is inefficient.
[0025] To address the aforementioned issues, this application provides a solution that controls the phased array antenna to move according to the motion information and reads the position and amplitude information of the phased array antenna in real time. After the phased array antenna completes its movement, the position and amplitude information are comprehensively analyzed to obtain the error values of each antenna in the phased array antenna. In this way, the pointing accuracy test and calibration are completed in a single unified movement.
[0026] After introducing the basic principles of this application, various non-limiting embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0027] Exemplary method Figure 1 This is a flowchart illustrating a pointing accuracy motion testing method provided in one embodiment of this application. Figure 1 As shown, the method includes the following:
[0028] Step S110, obtaining basic information of the phased array antenna; The purpose of this step is to collect the basic parameters and configuration information of the phased array antenna, which is crucial for subsequent testing and analysis. Specifically, the basic information includes but is not limited to the model of the antenna, array configuration, operating frequency, number of array elements, phase control method, etc. These information can be obtained through technical documents, user manuals or directly from the antenna control system.
[0029] Step S120, determining the motion information of the phased array antenna based on the basic information; Wherein, during the process of the phased array antenna moving according to the motion information, each theoretical pointing beam in the phased array antenna is in the time period of the test position; Specifically, according to the basic information of the antenna, the motion trajectory, speed and other related parameters in the test process are determined. In practical application, the physical and electrical characteristics of the antenna are analyzed, and an optimal motion path is designed to ensure the comprehensiveness and efficiency of the test. This involves calculating the scanning range, step angle and expected test position of the antenna. Detailed motion parameters, including motion trajectory, speed, test position, etc., are used to control the actual motion of the antenna.
[0030] According to the scanning range requirements of the phased array antenna (determined by the operating frequency range and application scenario) and the array element arrangement, the trajectory of the antenna motion driven by the mechanical arm or turntable is designed. According to the motion trajectory and speed, the time period required for the phased array antenna to complete a complete motion is calculated. This period should ensure that each theoretical beam of the antenna has enough time to point to the test position during the motion process, and enough number of data points can be collected. For example, for a phased array antenna with a specific motion trajectory and speed, the calculated motion period should ensure that each theoretical beam can be tested when it points to different beam pointing positions, and enough dense data can be collected at key positions (such as areas with large beam pointing changes) to accurately analyze the beam pointing error.
[0031] Step S130, controlling the phased array antenna to move according to the motion information, and reading the position information and amplitude value information of the phased array antenna in real time; The actual test process needs to control the motion of the antenna and monitor its performance in real time. Specifically, using mechanical or electronic control system, the motion of the antenna is accurately controlled according to the motion information determined in step S120. At the same time, using sensors and measuring devices, the position and amplitude value information of the antenna are read in real time. Real-time position and amplitude value data provide raw data for subsequent data analysis Step S140, after the phased array antenna completes the movement, the position information and amplitude value information are comprehensively analyzed to obtain the error value of each antenna of the phased array antenna; By analyzing the collected data, the deviation between the actual pointing direction of the antenna and the expected pointing direction is calculated. Specifically, using data processing software or algorithm, the actual amplitude value and position information of the antenna are compared with the theoretical model or expected value, and the pointing error of each antenna unit is calculated. Through the above steps, the error value of each antenna unit can be obtained, which indicates the deviation degree of the antenna performance.
[0032] Step S150, compensating the phased array antenna based on the error value, and repeating the above steps until the error value of each antenna is less than the preset range.
[0033] Specifically, the antenna performance is adjusted through compensation measures to meet the expected accuracy requirements.
[0034] According to the error value obtained in step S140, the phase control or other related parameters of the antenna are adjusted to correct the pointing error. Then steps S110 to S140 are repeated until the error value of all antenna units is within an acceptable range. The corrected antenna performance can ensure that the error value of each antenna unit meets the preset accuracy requirements.
[0035] Through these steps, the testing and correction process of the phased array antenna can be automated and precisely controlled, thereby improving the performance and reliability of the antenna. This method is particularly suitable for applications that require high-precision beam pointing, such as radar, satellite communication and navigation systems.
[0036] In some embodiments, the movement of the phased array antenna is controlled by a mechanical arm. The control of the phased array antenna according to the movement information includes controlling the phased array antenna to move according to the movement information through the mechanical arm.
[0037] The mechanical arm usually adopts a multi-joint structure, and each joint is equipped with a high-precision motor and a reducer to realize precise position control. For example, a common six-degree-of-freedom mechanical arm, its six joints can move flexibly in space, driving the phased array antenna to reach the specified position. The motor uses a servo motor, which can accurately control the speed and angle according to the instructions of the control system, and the reducer is used to increase the torque to ensure that the mechanical arm can stably carry and move the phased array antenna.
[0038] The driving system of the robot arm includes motor drivers, controllers, power supplies, and other parts. The motor driver receives the control signal from the controller, converts it into the current and voltage required by the motor, and drives the motor to operate. The controller is responsible for generating control signals according to the preset motion information, coordinating the motion of each joint, and achieving precise trajectory tracking and positioning control of the robot arm. The power supply provides stable power support for the entire driving system to ensure the normal operation of the robot arm.
[0039] Advanced trajectory planning algorithms, such as cubic spline interpolation or quintic polynomial interpolation, are used to generate the motion trajectory of each joint of the robot arm based on the motion information of the phased array antenna, including the motion trajectory, speed, and acceleration requirements. These algorithms can ensure that the robot arm smoothly and accurately reaches the target position during the motion process, and the speed and acceleration change continuously on the motion path, reducing the impact and vibration on the phased array antenna, and facilitating the acquisition of accurate test data.
[0040] Closed-loop control algorithms, such as proportional-integral-derivative (PID) control algorithms, are used to monitor the actual position and speed of the robot arm joints in real time and compare them with the preset motion information. According to the error signal, the output of the motor is adjusted to enable the robot arm to quickly and accurately track the preset trajectory. The PID controller optimizes the control performance by adjusting parameters such as the proportional coefficient, integral time constant, and differential time constant, improving the positioning accuracy and dynamic response characteristics of the robot arm.
[0041] The robot arm can achieve high-precision position control, with a positioning accuracy of millimeters or even higher. In the pointing accuracy test of the phased array antenna, this high-precision positioning capability can ensure that the antenna accurately moves to the vicinity of the theoretical pointing position for testing, thereby obtaining accurate amplitude value information. For example, for a precision measurement radar antenna that requires beam pointing accuracy to be one-tenth of a milliradian, the high-precision positioning of the robot arm can enable the antenna to perform accurate testing within a small angle range, improving the accuracy of the test results.
[0042] The robot arm also has high repeatability accuracy, with minimal deviation when repeatedly moving to the same position. This is very important for the phased array antenna pointing accuracy optimization process that requires multiple iterations of testing and compensation. In each iteration, the robot arm can accurately move the antenna to the same test position, ensuring consistency of test conditions, making each set of test data comparable, and facilitating accurate evaluation of compensation effects and speeding up convergence to a state that meets the preset accuracy requirements.
[0043] In some embodiments, comprehensive analysis is performed, including: analysis using a difference pattern search pointing method to determine the actual pointing of the antenna beam; and searching for the angle value corresponding to the minimum amplitude value to determine the main lobe direction of the antenna beam.
[0044] The error value is the difference between the actual beam pointing and the theoretical pointing.
[0045] The error value is a key indicator of the accuracy of the phased array antenna beam pointing, which directly reflects the degree of deviation between the actual beam pointing and the theoretical pointing. In an ideal case, the antenna's beam should accurately point to the predetermined theoretical direction, but due to various factors (such as antenna design errors, manufacturing process deviations, environmental influences, etc.), the actual beam pointing often deviates from the theoretical pointing, and this deviation is quantified by the error value. The calculation of the error value is to subtract the theoretical pointing angle from the actual beam pointing angle, i.e. error value = actual beam pointing angle - theoretical pointing angle.
[0046] The motion information includes: motion start and end points, and motion trajectory.
[0047] The design of the motion trajectory should be optimized according to the scanning requirements and performance characteristics of the phased array antenna. For antennas that need to be scanned in all directions, circular, elliptical or spiral trajectories may be used to ensure that the antenna can uniformly cover all directions in space. For example, in radar applications, in order to achieve comprehensive monitoring of the surrounding airspace, the motion trajectory of the phased array antenna can be designed as a circular trajectory, so that the beam can be directed to different azimuth and elevation angles in turn. When designing the motion trajectory, the motion speed and acceleration requirements of the antenna should also be considered. The trajectory should ensure that the speed and acceleration of the antenna change smoothly during motion, avoiding sharp changes that may cause antenna vibration or mechanical component wear. Mathematical curve fitting and optimization algorithms, such as spline curve interpolation, polynomial fitting, etc., can be used to generate smooth motion trajectories according to the given motion start and end points and speed and acceleration constraints.
[0048] Reasonable motion trajectory helps to improve test accuracy. By accurately designing the trajectory, the antenna can stay in key positions (such as areas with large changes in beam pointing or areas with expected large errors) for sufficient time or collect more data points during testing, thus more accurately obtaining the performance information of the antenna. For example, in areas with high beam pointing accuracy requirements, the motion speed can be appropriately reduced, and the data collection density can be increased to improve the detection capability of small errors.
[0049] The motion trajectory also directly affects the test efficiency. If the trajectory is not reasonably designed, it may lead to excessive test time or repeated motion, wasting resources. For example, overly complex or circuitous trajectories will increase the motion distance and time of the antenna, reducing test efficiency. Therefore, under the premise of ensuring test accuracy, the shortest and most direct motion trajectory should be selected, taking into account the motion characteristics of the antenna and the performance of the test equipment, to improve the efficiency of the entire test process.
[0050] Real-time reading of phased array antenna position information and amplitude value information, including: when there is a preset test position of an antenna, collecting amplitude value information. That is: only when the antenna is at the preset test position, the amplitude value is collected, which can reduce unnecessary data collection and storage. If the amplitude value is collected uninterruptedly during the entire movement process, a large amount of redundant data will be generated, increasing the data processing burden and time cost. While collecting data at key test positions, the amount of data can be more concise, facilitating subsequent data management and analysis, and improving the data processing efficiency of the entire test process. At the same time, in the data processing stage, the collected data can be classified and processed directly according to the relevant information of the preset test position, without the need to screen a large amount of useless data, further optimizing the data processing process.
[0051] The scheme provided by the application will be further described below in combination with various preferred embodiments: Specifically, referring to Figure 2 The specific process of the scheme provided by the application is as follows: 1. Initialize parameters, obtain test key information from the parameter configuration interface: test frequency, test theoretical beam pointing.

[0057] 7. Obtain the pointing error value corresponding to each beam according to the data analysis, and store and record 8. Control the mechanical arm to move according to the movement range again.

[0059] 10.
