摘要：To enhance the computational efficiency and precision of classical interferometric SAR(InSAR) imaging geometry simulation, computer graphics method was firstly introduced into imaging geometry simulation, the OpenGL graphics library and Z-Buffer algorithm were used to complete the shadow computation, the pixel operation and graphics transform method were used to densify the sampling points and complete the coordinate computation. Imaging geometry was verified by the process of echo simulation, imaging and interferometric processing, the experimental results showed that the method has the characteristics of high precision and good efficiency
