摘要

星载合成孔径雷达(SAR)在瞄准运动舰船时，图像会出现离焦和模糊。针对这一问题，提出了一种将压缩感知(CS)与时频分布(TFD)相结合的船舶图像增强方法，提高了成像效果，得到了一系列不同方位时间下船舶姿态变化的图像。通过对SAR实测图像的处理，验证了该方法的有效性。

A vessel imagery enhancement method of spaceborne SAR based on CS-TFD

The spaceborne synthetic aperture radar (SAR) image would become defocused and fuzzy when aiming to a moving vessel. To solve the problem, a vessel imagery enhancement method combining compressed sensing (CS) with time frequency distribution (TFD) is presented, by which, the imaging result is improved, and a series of images at different azimuth time are obtained showing the vessel posture changing. The validity of the method is verified by processing a measured SAR image.
