Problems solved by technology

[0004] However, the existing combination technology of mechanical adjustment and phase adjustment needs to realize the phase adjustment based on the feedback information after the mechanical adjustment is completed, which leads to the prolongation of the tilt adjustment control time of the entire phased array antenna, and in high-frequency, large-scale scanning applications Under the environment, the amplitude of mechanical adjustment fluctuates greatly, which is not conducive to the timely, stable and accurate scanning of the phased array antenna; Flexible adjustment of the inclination angle of the entire phased array antenna

Abstract

The invention discloses a phased array antenna inclination coordinated adjustment method, system, terminal and medium, and relates to the technical field of phased array antennas. The key points of the technical solution are: establishing a mechanical dynamic adjustment model; Calculate the ratio of the maximum value of the azimuth scanning range of the antenna to obtain the synergy coefficient; input the synergy coefficient into the mechanical dynamic adjustment model to calculate the mechanical adjustment azimuth; obtain the corresponding error correction angle according to the synergy coefficient matching, and combine the theoretical compensation azimuth and mechanical adjustment The azimuth angle is calculated to obtain the actual compensation azimuth angle of the phased array antenna scanning; after the actual compensation azimuth angle is converted into the compensation phase, the phase shift adjustment is performed on the phased array antenna, and at the same time, the mechanical control platform is controlled according to the mechanical adjustment azimuth angle and the compensation pitch angle. Realize the cooperative adjustment of scanning inclination. The invention synchronously and dynamically adjusts the phased array antenna and the mechanical control platform, which is beneficial for the phased array antenna to complete scanning in a timely, stable and accurate manner.

Description

technical field [0001] The present invention relates to the technical field of phased array antennas, more specifically, it relates to a method, system, terminal and medium for coordinated adjustment of phased array antenna inclination. Background technique [0002] The phased array antenna is an antenna that changes the shape of the pattern by controlling the feed phase of the radiating elements in the array antenna. Controlling the phase can change the direction of the maximum value of the antenna pattern to achieve the purpose of beam scanning, that is, the phased array antenna array Face inclination adjustment. Compared with the traditional mechanical scanning antenna, electronic phase shifting is used to realize the inertialess high-speed scanning of the beam. Its electromagnetic wave beam pointing control is flexible and the tracking speed is fast, which can ensure the real-time high-precision star alignment of the antenna under high-speed moving conditions; and throug...
