摘要
根据SAR的特点,本文提出一种星载合成孔径雷达(SAR)成像处理方法。分别对星载SAR处理的雷达回波信号、距离处理、方位处理、多视处理和多普勒参数估计几个主要部分进行了分析和讨论。对地面原始图像和包括方位处理、距离徙动校正、多视处理和运动补偿的星载SAR成像处理进行了计算机仿真。计算机仿真结果表明该方法是有效的。
A method is proposed to perform the spaceborne Synthetic Aperture Radar (SAR) imaging processing based on the characteristics of SAR in this paper. Several important parts are analysed and discussed, which include echo signal, azimuth processing, range processing multi-looks processing and Doppler parameters estimation for spaceborne SAR. The computer simulation of terrain and spaceborne SAR imaging processing are made, which includes azimuth processing, range migration correction, multi-looks processing and motion compensation. The result of computer simulation shows that this method is effective.
