The accurate model for beam synchronization in spaceborne/airborne hybrid bistatic SAR

An accurate model for beam synchronization in spaceborne/airborne hybrid bistatic SAR (SA-BSAR) system is proposed. In this model the accurate and real-time steering of receiver´s antenna on airborne platform is realized. The main characteristics of this model are proposing the accurate geometric model and applied control model. When the information of antenna´s beam on the spaceborne platform can be forecasted or measured, the high precision of the azimuth angle and elevation angle of receiver´s antenna is guaranteed. The proposed model could be easily applied and is economic.
