Abstract :
This paper proposes a scheme of bistatic SAR with three channels for ground moving targets detection. According to the characteristic of bistatic SAR, FrFT technique was chosen to focus the moving target and improve the signal to clutter ratio, while we suppress clutter and estimate the parameters of moving target with clutter suppression interferometer techniques. From the spatial geometry model and echo signal model of the system, the method of moving target parameters estimation was carried out. Computer simulation results validate ground moving targets detection can then be obtained by jointly processing algorithm.
