机载双基地SAR成像算法的FPGA设计与实现

双基地合成孔径雷达(简称双基地SAR或Bistatic SAR)是一种新的成像雷达，也是当今SAR技术的一个发展方向，在军用及民用领域都具有良好的应用前景，近年来成为研究的热点。本文则侧重于研究双基地SAR的距离一多普勒(R-D)成像算法的实现。在双基地SAR系统及成像算法的研究方面，推导了双基地SAR的系统分辨特性及雷达方程，分析了主要系统参数之间的约束关系。针对正侧视机载双基地SAR系统，本文对距离一多普勒算法进行了推广。最后得到点目标的仿真结果。在成像算法的FPGA实现上，在System Generator环境下对算法进行定点仿真。完成距离一多普勒成像算法的硬件实现，其中包括了FFT快速傅立叶变换、硬件乘法器、：Rocket I/O接口设计、DCM数字时钟管理等主要部分。针对硬件实现的特点，对算法的部分运算进行了简化。为了对算法实现进行验证，设计开发了该算法的硬件测试平台。主要基于ML310评估板上XC2VP30芯片中嵌入的Power PC 405，完成其硬件部分的设计，主要包括了Aurora协议接口、RS-232串行接口、DDR RAM接口以及其它如中断、时钟等部分。
