摘要
为获得雷达波束斜视时InSAR成像的特点,对系统仿真提供理论指导,修正了传统InSAR的成像原理,推导了SAR图像几何校正后斜视角对InSAR干涉相位图的影响,并给出了平地效应条纹变化和地形高度效应的解析表达式,仿真验证了斜视InSAR和正侧视InSAR的差异。
In order to obtain the characteristics of interferometric synthetic aperture radar （InSAR） with squint angle and provide theoretic guidance for system simulation,the principle of conventional InSAR was modified,and the effect of squint angle on the interferogram after SAR images＇ geometrical calibration was proposed,and then the analytic expression of flat earth effect and terrain height effect were given.Simulation results give the difference between squint InSAR and conventional InSAR.
