摘要

摘要: 为满足基于模板的SAR地面车辆目标识别对海量高质量模板图像的工程应用需求,该文提出了一种基于射线追踪技术的SAR信号级高效仿真方法.该方法通过构建地面车辆目标SAR仿真场景物理模型并利用射线追踪方法准确模拟SAR探测过程中电磁波与场景中目标与环境的作用机理,实现对地面环境的宽带相干杂波、表面粗糙的复杂目标的宽带电磁散射以及地面-目标间耦合散射的快速计算,并通过SAR成像处理和图像相似度评估确认形成高质量SAR模板图像.数值结果验证了该文方法的准确性和高效性.

Abstract: Aiming at meeting the requirement of the amass high-quality SAR images needed by template-based ground target recognition engineering practice, a novel efficient SAR signal level simulation method is proposed. The electromagnetic scattering interaction mechanisms including coherent clutter of ground, multiple reflection and edge diffraction of vehicle, coupling-scattering between vehicle and ground are accurately estimated by utilizing an efficient ray-tracing technique. High quality SAR images are finally created through the SAR imaging procedure. Simulation results show that, the new method is feasible and effective.
