Study of Effect of Raw Data Compression on Azimuth Multi-channel SAR System

Leida xuebao, 2017
An effective way to achieve High Resolution and Wide Swath (HRWS) imaging capability is the multi-channel technique in azimuth. Improved resolution and swath can dramatically increase the volume of echo data in the SAR system.
