摘要
合成孔径雷达(SAR)是一种具有广泛用途的全天候高分辨力成像雷达。由于微波图像与实际物体的视觉形象大不相同,从而使SAR的图像质量评估体系较其它成像系统更难建立。本文根据星载SAR成像算法研究的需要,从成像角度分析和研究了影响SAR图像质量的主要参数,建立了SAR图像质量评估系统,并给出了初步的测试方法。
The synthetic aperture radar (SAR), as an all-weather active highresolution imaging radar, is widehy applied in many fields. As microwave image is different from the real target, it is difticult to establish a quality parameter system for SAR image. The main parameter to affect SAR image are analysed, the definition and the measuring methods of which are given here.
