Antenna Tracking and Angle Measurement Algorithm of Communication in Motion Based on Pseudo Monopulse Technology

Monopulse tracking is to generate multiple beams in one pulse period at the same time, so as to determine the azimuth and pitch errors; The pseudo monopulse tracking system is a simplification of monopulse tracking system, which generates the tracking beam alternately at the center, top, bottom, left and right of the main beam in time order. According to the characteristics of the alternate generation of pseudo monopulse tracking beams, a tracking angle measurement algorithm is proposed. In the alternate generation of pseudo monopulse tracking beams, the principle of amplitude comparison and direction finding is used to analyze the change law of the relationship between the level difference between the upper and lower beacons. The level difference between the left and right beacons and the angle difference between the antenna and the satellite signal beam center. The controller compares the stored information. The azimuth and pitch deviation are estimated, and the antenna beam center is adjusted. The simulation results show that in the pseudo monopulse tracking system. The angle measurement algorithm can achieve higher accuracy.
