23909 FMCW InSAR 系统由于载机平台高度低，气流扰动严重，位置和姿态变化大，且微机电系统惯性测量单元(MEMS IMU)测量精度低，导致系统出现较大的时变基线，严重影响数字高程模型(DEM)精度。 For airborne dual-antenna FMCW InSAR systems, the time-varying baseline can be considerably high due to its low flight height, atmospheric turbulence, location and attitude errors and low accuracy of MEMS IMU, seriously affecting the DEM accuracy.
