Abstract :
This paper studies the SAR signal processing in subsurface radar. According to the principle of multiple scatter-point localization, the point-to-point correlation method is derived to solve the near-field problem. The Snell law is applied to correct the refraction caused by different media. The simulation results demonstrate that the presented method can implement SAR signal processing and imaging in subsurface radar
