摘要
针对电大尺寸目标与复杂场景融合的合成孔径雷达(SAR)成像问题,通过对目标的精细建模及复杂场景的布设,分别采用双向解析射线追踪算法和映射投影算法计算电大尺寸目标和复杂场景的电磁散射,获得电大尺寸目标与复杂场景融合的SAR成像结果。在实现目标高精度SAR成像仿真的同时,兼顾了大范围场景SAR成像仿真的效率,为目标与复杂场景融合SAR成像仿真提供了一种有效途径。
Aiming at the problem of the synthetic aperture radar(SAR)imaging of the fusion of electrically large targets and complex scenes,the fine modeling of target and the layout of complex scenes are carried out.The electromagnetic scattering of electrically large targets and complex scenes are calculated by the bidirectional analytical ray tracing(BART)algorithm and the mapping and projection algorithm(MPA)respectively,then the SAR imaging results could be obtained.While realizing the high-precision SAR imaging simulation of targets,it also considers the efficiency of large-scale scenes SAR imaging simulation,which provides an effective way for the SAR imaging simulation of fusion of targets and complex scenes.
