摘要/Abstract

摘要： 为提高典型目标SAR图像仿真的保真度,本文提出了适用于分布式目标的顾及多次散射的光线追踪辅助SAR图像仿真方法。在距离多普勒(RD)成像几何关系约束下,采用SAR空间遍历模式进行雷达波束时变辐射区判别及电磁波发射模拟;结合光线追踪算法与物理光照模型进行电磁波多次散射场计算,实时记录分布式目标的多次散射幅度和相位;将朝向波束辐射区内所发射电磁波的后向多次散射子场进行矢量叠加,即可生成分布式目标的后向散射总场即原始回波信号;采用RD成像算法处理仿真回波,生成对应SAR仿真图像。选取典型舰船目标开展SAR图像仿真试验,并分别与实测图像及主流商业仿真软件的仿真结果进行综合对比分析,以验证所提方法的有效性。

Abstract: In order to improve the fidelity of distributed target SAR image simulation,we propose a novel ray tracing-assisted SAR image simulation method including multiple scattering.This method utilizes the range Doppler (RD) imaging geometry and ray casting theory to discriminate the radar beam radiation area of distributed targets and simulate the electromagnetic waves transmission.The ray tracing algorithm and the physical illumination model are combined to simulate the multiple scattering of EM waves,and the multiple scattering amplitude and phase are recorded in real time.The raw echo signal of the distributed targets is processed by RD imaging algorithm,then the corresponding SAR simulated image is obtained.We select some typical distributed targets to simulate SAR images,and then compare the simulated results with the real SAR images and the simulated results of the mainstream commercial simulation software to verify the effectiveness of the proposed method.

Key words: SAR image simulation, ray tracing, multiple backscattering, echo simulation
