Application of MoM-PO hybrid technique in complex target high resolution imaging simulation

Simulation and modeling of complex targets high resolution imaging by electromagnetic calculating method is very important for high resolution radar targets detection and automatic recognition. In the process of calculating the high resolution image of electrically large targets, high-frequency approximation method and low frequency numerical method have their respective superiorities and limitations, so it is a feasible method to combine the two methods to calculate. In this paper, the high resolution information in wideband frequency of the target with arbitrary shape and in arbitrary attitude is simulated by MoM-PO hybrid techniques for accurate and efficient analysis of scattering fields, and the high resolution range profile (HRRP) and two-dimensional images of the complex target is simulated with these wideband responses. The simulation results show that this hybrid method is effective and applied in high resolution imaging for complex real targets. (4 pages).
