Abstract :
This paper reports a real-time motion compensation (MoCo) strategy of a P band airborne UWB SAR. The strategy includes three parts: stabilization of the antenna to compensate the rotational error of the platform, real-time Pulse Repetition Interval (PRI) adjustment to compensate the along-track velocity variation and MoCo across the track. Finally, real-time imaging result of the UWB SAR is present.
