%X An existing approach for beam synchronization, which is based on antenna steering on both sides, can not be applied to Spaceborne/Airborne hybrid Bistatic SAR (SA-BSAR) systems using sources of opportunity since the transmitter beam can not be steered. An approach via wide-beam receiving is proposed. The inspiration comes from the fact that the receiving distance in SA-BSAR is much shorter than the one in spaceborne SAR systems. An approach for compensating the estimation error of the satellite overpass time and the error in the aircraft navigation system is also proposed. The compensation is implemented through the processing of the direct path signal. The results of the performed simulation show that it can achieve a useful scene extension (at least more than 1 km) with an azimuth resolution slightly superior to the one obtained in spaceborne SAR systems.
