A discussion on a new method of wide swath SAR
一种宽测绘带SAR新方法的探讨

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.
