摘　　要：介绍了机载SAR雷达成像对天线指向的要求和稳定平台的系统组成,详细推导了坐标正变换和坐标反变换算法,给出了单片机汇编语言软件框图,经过仿真计算证明其精度可以达到成像要求。This paper introduces the demand of radar imaging on antenna direction and the composition of the three axis stabilized platform.It also educes the coordinate transformation algorithm particularly, and presents the software frame with single chip computer assemble language. Simulation proves that the accurary of the algorithm can meet the requirement of imaging.

关 键 词：机载SAR 稳定平台 坐标变换 天线指向 汇编语言
