An Advanced Approach to Improve Synchronization Phase Accuracy with Compressive Sensing for LT-1 Bistatic Spaceborne SAR

Remote Sensing, 2022
In the bistatic synthetic aperture radar (BiSAR) system, the unavoidable frequency deviation between the oscillators (USOs) will result in additional phase modulation in the demodulated radar signal, which significantly degrades the quality of the SAR ...

LuTan-1: First Demonstration of Hybrid-Polarimetric Synthetic Aperture Radar—Assessing Application Potentials and Performance Constraints

Journal of Remote Sensing
The hybrid-polarimetric (HP) mode is an emerging synthetic aperture radar polarimetric mode that offers a wider swath and improved range ambiguity performance compared to the quadrature-polarimetric (QP) mode, with a slight loss of polarimetric ...
