Abstract

The invention provides a satellite tracking method, which relates to the field of electromagnetic wave beam tracking, and is used for realizing the rapid tracking and pointing of satellites. The method comprises the steps that the directivity factor function of the antenna is obtained; the Jacobi matrix of the directivity factor function which is used for determining the angle compensation direction of the antenna is obtained; the angle of deviation matrix of the antenna, relative to the satellite can be obtained through scanning, and the angle of deviation matrix is used for providing a function model to obtain the compensation angle; the compensation angle is obtained based on the directivity factor function, the angle of deviation matrix, and the Jacobi matrix, and the compensation angle is used for guiding the antenna to move at the next time; the compensation angle can be dynamically obtained during the aligning process, the antenna is continuously adjusted based on the compensation angle to scan, track and align the satellite. The invention is advantageous in that the satellite tracking errors can be rapidly converged through collecting wave beam signals having quite a few orquite low frequency, and the satellite aligning with high precision can be realized.

Description

technical field [0001] The invention relates to the field of electromagnetic beam tracking, in particular to a satellite tracking method. Background technique [0002] Accurate capture and tracking of satellite signals has always been a core indicator of satellite antennas. Most of the current automatic satellite tracking methods involve hardware analysis of the power level value rssi of satellite signals for beam signal indication. The current satellite tracking algorithm is a simple processing of the signal value of the satellite beam, by stepping and scanning near the incoming beam, searching for the maximum point of the signal, as the basis for star alignment, the signal processing method is very simple. There is a large time delay, the error is also large, and the accuracy needs to be improved. [0003] Moreover, part of the scanning method is only based on finding the position of the maximum received signal. This processing mechanism has no problem for unilateral rece...
