HRRP Analysis of Composite Model from a Target above Rough Ground

Abstract

In the paper, high resolution range profile (HRRP) of a target above rough ground is analyzed based on the scattered echo data. The electromagnetic scattering of composite model is solved by the hybrid method of physical optics (PO)- shooting and bouncing ray (SBR). And an octree data structure is used to accelerate the ray tracing progress. The bistatic electromagnetic scattering of a reduced-scale vehicle target above rough ground is calculated by our method and compared with the simulation result with MLFMM in FEKO. Then by inverse Fourier transform of backscattering echo data, the range profile of composite model is obtained.
