  • Abstract
    A modified wavefront reconstruction algorithm (MWRA) is proposed for imaging a subsurface layer for a vehicle- or air-borne SAR. The MWRA with refraction and dispersive effect compensation can improve image quality and locating accuracy compared with the traditional one. Associated with the relax-based depth estimation method, the MWRA can provide 3D location information of multiple buried targets. Some simulated results show the effectiveness of the modified algorithm.
