英文摘要：

The wide swath SAR （ScanSAR model） has some advantage, such as wider swath and short interval, and it can form interferometry with else SAR models for example IM model, so that more interference images can be generated in data processing. Therefore, ScanSAR model can be used in deformation, especially small deformation survey in the future. In this paper, wide swath SAR imaging algorithm is introduced and the interference of different SAR models are expatiated. In the end, development direction about wide swath SAR, for example, interferometry between WSM and IM model, atmosphere correction algorithm based on WSM , application and study of CR and PS technique for WSM, are introduced especially.
