Improved Phase Gradient Autofocus Method for Multi-Baseline Circular Synthetic Aperture Radar Three-Dimensional Imaging

Improved Phase Gradient Autofocus Method for Multi-Baseline Circular Synthetic Aperture Radar Three-Dimensional Imaging

Multi-baseline circular synthetic aperture radar (MB CSAR) can be applied to obtain a three-dimensional (3D) image of the observation scene. However, the phase error caused by radar platform motion or atmospheric propagation delay restricts its 3D imaging capabilities. The phase error calibration of...
