Search Strategy of Shipborne Satellite Communication Servo with Changing Heading

Abstract

Aiming at the problem of the ship-borne satellite communication servo system cannot reliably search the target under changing heading, the corresponding search strategy is studied to achieve the goal of reliable search. Starting from deck angle calculation model of ship-borne satellite communication station, this paper studies the problem of searching strategy of satellite communication station under changing heading, puts forward that real-time heading variable is introduced in searching stage to solve the problem that searching center point is difficult to find target center point without changing heading. Starting from setting threshold of signal-to-noise ratio of satellite beacon, an improved main and side lobe searching strategy is proposed, which effectively solves the problem of existing system. The actual testing results show that the proposed method can effectively improve the performance of the ship-borne satellite communication servo system with changing heading.
