In order to achieve the best interferometric performance, the on-orbit alignment of the antenna beams [1] of dual-antenna single-pass synthetic aperture radar (SAR) interferometry is a key requirement. Meanwhile, for geosynchronous synthetic aperture radar [2] with the very large slant range from the radar to the mapped area, antenna pointing control system(More)
A clutter suppression algorithm for SAR imaging is proposed in this paper. The optimal waveform of the SAR system is designed according to the prior-knowledge of the target and clutter, an amplitude limiter set in frequency domain is used to suppress the clutter response and 2-dimensional pulse compression is then used to the SAR imaging. With the help of(More)
