Extended Chirp Scaling-Baseband Azimuth Scaling-Based Azimuth-Range Decouple L1 Regularization for TOPS SAR Imaging via CAMP.

This paper proposes a novel azimuth-range decouple-based L1 regularization imaging approach for the focusing in terrain observation by progressive scans (TOPS) synthetic aperture radar (SAR). Since conventional L1 regularization technique requires transferring the (2-D) echo data into a vector and reconstructing the scene via 2-D matrix operations leading to significantly more computational comple...
