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.

Imaging a Wide Swath with Full Polarimetry [PDF]
, 2015 Several applications of synthetic aperture radar (SAR) require or at least benefit from full polarimetry. In the past, however, full polarimetry has been often discarded in the design of spaceborne SAR missions, as it implied a significant reduction of ...

Data Volume Reduction in High-Resolution Wide-Swath SAR Systems [PDF]
, 2015 High-resolution wide-swath (HRWS) synthetic aperture radar (SAR) systems are very attractive for the observation of dynamic processes on the Earth’s surface, but they are also associated with a huge data volume.
