摘　　要：研究了惯性系统 ( INS) /合成孔径雷达 ( SAR)组合导航系统中导航误差的修正、雷达信号相位的调整及合成孔径雷达对捷联惯性元件误差的要求等问题 ,并给出了仿真结果。We initiated the research on integrated INS/SAR navigation system in China [7] . In this paper, we study the influence of the error of strapdown inertial units on synthetic aperture radar (SAR). In subsection 2.3 and 2.4, we analyzed the influence of the error of accelerometer and gyro on SAR mapping respectively. Based on the analysis, we give the allowable range for each error. Simulation results given in section 3 show that the integrated INS/SAR navigation system can achieve good performance when the value of the error are within the allowable range.
