Multichannel False-target Discrimination in SAR Images Based on Sub-aperture and Full-aperture Feature Learning

open access: yesLeida xuebao, 2021
False targets caused by multichannel Synthetic Aperture Radar (SAR) are similar to a defocused ship in both shape and texture, making it difficult to discriminate in the full-aperture SAR image.

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

open access: yesLeida 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 ...
