一种宽测绘带SAR新方法的探讨

A DISCUSSION ON A NEW METHOD OF WIDE SWATH SAR

宽测绘带SAR是当前星载合成孔径雷达研究的热点问题,在需要全球动态观察或高重复周期观察局部地区的应用中都希望能进行宽测绘带成像。该文论述了一种基于多调制方式的宽测绘带方法。并详细论述了调制方式的选择,盲区问题及其数据处理方法。

Wide swath SAR is a hotspot of the research of SAR (Synthetic Aperture Radar). In many fields of SAR application which require global and dynamic surveillance or frequent surveillance of a certain part of the earth surface, it is expected that the swath of SAR is much more wider. A new method of wide swath SAR based on multiple modulation mode is presented in this paper. The selection of modulation mode, the solution to the problem of blind zone, and the data processing method of this system are discussed.
