Bistatic SAR is gaining more and more interest over the last years, the detection and imaging of moving targets based on Bistatic SAR is also a crucial technique. In Bistatic SAR imaging, a moving target may induces a Doppler-shift and a Doppler-spread on the returned signal in the slow-time frequency domain, which results in position error and defocus phenomenon on imaging. This paper presents a tandem geometry configuration of Bistatic SAR and a motion model of the target firstly, then the influence of the motion target on the imaging of Bistatic SAR and the technique of detection and imaging of moving targets based on Bistatic SAR will be discussed.
