摘　　要：机载合成孔径雷达(SAR)通过载机相对固定地面的飞行运动形成合成孔径,获得高分辨率的雷达图像,具有全天候、全天时的特点,在军事和民用领域都取得了广泛的应用。介绍了基于通用硬件平台的机载SAR侧视条带成像中R-D算法的实现。通过优化软件设计,提高对开发板资源的利用效率,达到了实时处理的要求,实现了设计目的。Airborne SAR can achieve high resolution imaging by synthetic aperture of aircraft flight movement related to static ground. Because of its all-weather, day and night characteristics, SAR has been widely applied in both military and civilian areas. This paper introduces the implementation of Range-Doppler （R-D） algorithm in airborne SAR side-sight imaging on the TS-C43 board based on TS101. Through optimizing the software design, the processing capability of the board is greatly enhanced. It meets the need of real-time processing. The final result shows that the design is successful.
