Abstract :
Satellite attitude and antenna pointing design strategy is the key design issue of distributed spaceborne radar system design. In the case of noncooperative transmitter, the article presents six attitude and antenna pointing parameter strategies. Several mathematic methods are provided as follows. A general method of beam-pointing synchronization is summarized. Six methods of beam synchronization are provided, each corresponding to one of six attitude and antenna pointing strategies above. An approach of how to compute the requirement of control ability of attitude and antenna pointing is presented. In order to compare with performance of six parameter strategies, a swath overlap ability model is put forward. Lastly, a simulation case is presented, in which attitude and antenna pointing angles and swath overlap abilities of six parameter strategies are compared with each other. The simulation results prove correctness and validity of design methods.
