Abstract
According to the analysis of the moving process of conical scan, this paper proposes an improved tracking algorithm for airborne satellite communication( SATCOM) antenna, and theoretically deduces it by combining with the antenna radiation patterns and its 3D reconstruction method. Through curve fitting and Matlab simulation, it presents a formula to calculate the adjustment direction and angle. Finally, it analy-zes some problems to be focused in practice. Flight test demonstrates that the tracking algorithm improves the tracking accuracy and tracking speed of antenna servo system, and well meets the requirement of air-borne satellite communication.关键词
