Problems solved by technology

This method has the problem that the initial pointing position of the antenna is manually adjusted inaccurately when the phase calibration environment is unstable, resulting in low phase calibration accuracy. When dealing with inconsistent data in the phase calibration process, a simple average method is used, so the phase calibration accuracy can be improved. space

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] combine figure 1, shown in 2, the present invention provides a kind of phase compensation method based on the initial pointing error of the satellite station monopulse tracking receiver, by modifying the phase calibration program of the tracking receiver to realize the compensation of the phase of the manual phase calibration result, the specific steps are as follows:

[0043] Start the manual phasing process and manually adjust the antenna axis to point to the satellite;

[0044] Add a 'record' option in the tracking receiver, press the 'record' option, the program records the error voltage U of the azimuth axis at this time △A , the error voltage U of the pitch axis △E , and the error voltage gain coefficient α of the azimuth axis A , The error voltage gain coefficient α of the pitch axis E ;

[0045] Rotate the antenna E axis at...

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...
