nonlinear chirp scaling algorithm (NLCSA) and its extensions, such as extended NLCSA …

Abstract Spaceborne Synthetic Aperture Radar (SAR) is a well-established and powerful
imaging technology that can provide high-resolution images of the Earth's surface on a …

Since synthetic aperture technology was employed in radar signal processing, a lot of
imaging algorithms have been developed for highly squinted synthetic aperture radar (SAR) …

The high-resolution low frequency synthetic aperture radar (SAR) has serious range-
azimuth phase coupling due to the large bandwidth and long integration time. High …
