Abstract

The invention relates to a pointing error-based satellite communication station monopulse tracking receiver phase compensation method. Programs of a tracking receiver are modified, initial pointing errors of the pitch axis and the azimuth axis in the phase correction process are recorded, maximum voltage values of the E axis when the E axis rotates upwards and downwards are recorded during phasecorrection of the A axis, maximum voltage values of the A axis when the A axis rotates leftwards and rightwards are recorded during phase correction of the E axis, a compensation value is calculated through the recorded process quantity on the basis of a manual phase correction result, and the manual phase correction result is corrected. Accordingly, phase compensation on the manual phase correction result of the onboard satellite communication station monopulse tracking receiver is achieved, the phase correction precision during manual phase correction is improved, and the tracking performance of an onboard satellite communication station servo system and the channel quality of satellite communication links can be improved.

Description

technical field

[0001] The invention relates to the field of satellite communication station tracking receivers, in particular to a phase compensation method for a ship-borne satellite communication station monopulse tracking receiver. Background technique

[0002] The hull of the ship shakes all the time at sea. In order to establish stable communication, the shipborne satellite communication station mostly adopts a monopulse tracking system to realize the stable tracking of the communication antenna to the satellite. The tracking receiver is the key equipment in the servo system of the satellite communication station. It is responsible for demodulating the azimuth error and pitch error from the difference signal coupled from the antenna feed, and providing reference for the servo system to track the satellite. In order to accurately demodulate the azimuth and pitch error signals, it is necessary to calibrate the phase value of the tracking receiver, eliminate the phase dif...
