An Accelerated Algorithm Based on GO-PO/PTD and CWMFSM for EM Scattering from the Ship over a Sea Surface and SAR Image Formation

This article proposes an accelerated ray-tracing algorithm to improve the computational efficiency of composite scattering from the 3-D ship target located on a random sea surface. The ray tracing is accelerated by using a new neighbor search technique, with a new 0-1 transformation rule and arrangement of octree nodes. It can reduce the code complexity and improve the computational efficiency. Co...
