doi:10.3969/j.issn.1000-1093.2014.08.018

Abstract

Abstract: A dynamic processing method of roll angle of small floating maritime satellite antenna, which is applied in military concealed reconnaissance, is studied. The influence of roll angle on the quality of communication, the relation between azimuth and roll angles as well as the relation between elevation and roll angles are studied in theory. A dynamic processing method of that the compensations of the azimuth and elevation angles are applied to isolate the influence of the roll angle on communication is proposed. The relational expression among AGC, azimuth and elevation is fitted by the least square method based on the sampling data. The proposed method for roll angel of the small floating antenna is feasible by comparing the changes of AGC in the process of dynamic processing to the changes of AGC in the process of 4-axis servo compensation.

Key words: control science and technology, satellite communication, small floating antenna, roll angle, azimuth, polarization angle
