The invention belongs to the technical field of antenna flatness control, and discloses a flatness control method, device and application of a distributed large-scale phased array antenna, which divides the large-scale phased array antenna into multiple actively adjustable sub-arrays; Determine the pose and flatness of the current antenna array through the laser radar, find the optimal target pose through the Monte Carlo method, take the minimum adjustment as the optimization goal, and determine the target pose of each sub-array in the workspace; Carry out motion trajectory planning, drive the adjustment mechanism to achieve the target pose, and design a distributed front collaborative control virtual prototype model verification. Compared with the traditional method of directly decomposing the overall index into each local structure in the design stage, the present invention overcomes the thermal deformation of the antenna, the manufacturing error of the array, the motion error of the driving motor of the deployment mechanism, and the vibration received during operation in the actual working condition. The adverse effects of factors such as the influence of other factors, so the flatness of the antenna front is effectively guaranteed in practical applications.
Description
technical field [0001] The invention belongs to the technical field of antenna flatness control, and in particular relates to a flatness control method, device and application of a distributed large-scale phased array antenna. Background technique [0002] At present: active phased array radar has the advantages of flexible and controllable beam and high reliability, and its application in ground fixed radar and spaceborne radar has become increasingly widespread. With the continuous improvement of detection distance and detection accuracy requirements, radar antennas are developing towards large apertures. Especially for high-frequency active phased array radar antennas, the installation accuracy of the array structure is constantly improving, often at the submillimeter level. As the core part of phased array radar, the antenna array has a close relationship between its flatness and the comprehensive performance of the radar system. According to the theory of antenna struct...
