Hybrid Dual-Polarization Synthetic Aperture Radar

Remote Sensing, 2019
Compact polarimetry for a synthetic aperture radar (SAR) system is reviewed. Compact polarimetry (CP) is intended to provide useful polarimetric image classifications while avoiding the disadvantages of space-based quadrature-polarimetric (quad-pol) SARs.

Four-dimensional SAR Imaging Algorithm Based on Iterative Reconstruction of Magnitude and Phase

Leida xuebao, 2016
Observation data obtained from the Four-Dimensional (4D) Synthetic Aperture Radar (SAR) system is sparse and non-uniform in the baseline-time plane. Hence, the imaging results acquired by traditional Fourier-based methods are limited by high side lobes ...
