| Abstract: | 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. |
