摘要 通过对机载干涉合成孔径雷达(InSAR)常用的干涉参数定标方法——基于敏感度方程的干涉定标的仿真实验,分别在逐步增多需要定标的干涉参数个数和增大干涉参数偏差量的情况下,深入研究了这种定标方法对参与定标的干涉参数数目及干涉参数偏差边界值等的限制条件,结果表明,该方法在多干涉参数和大偏差条件下可以实现有效校准。 By means of imitation experiment on the interferometric parameter calibration method based on sensitivity equations for airborne interferometric synthetic aperture radars (InSAR), the authors did the research on the requirements of the calibrated parameter number and the error capacity. The results show that this method can realize the interferometrie parameters calibration even with more required calibrated parameters and larger errors of parameters.
