摘要
星载宽幅SAR也称为ScanSAR,其干涉测量是一种宽测绘带的三维测高和变形监测模式。本文介绍了ScanSAR模式(Wide Swath Mode,WSM模式)干涉测量及其与IM模式(Image Mode)联合干涉测量的方法,提出ScanSAR干涉数据处理的具体实现方案,并通过实例验证了ScanSAR干涉测量不仅能得到与IM模式同样的监测结果,而且其覆盖面较广,易发现大范围的变形,尤其是大区域的缓慢形变。
Interferometry with Space-borne ScanSAR is a wide swath elevation measurement technique.The method of ScanSAR mode （WSM mode） and WSM/IM Interferometry were introduced in this parer.A novel data processing method for ScanSAR interferometry was proposed.Validation of ScanSAR interferometry was proved by using an example,that is to say,ScanSAR interferometry not only could gain alike monistoring results with IM interferometry,but also had wider swath and dicover easily large-scale defomation,especially small deformation in the future.
