摘要
根据电磁散射理论,结合雷达目标的频率特性,运用高频散射机理分析方法和空间解析几何知识,对现有 ISAR 成像仿真系统中目标散射模型的遮挡函数进行了分析,并在此基础上对遮挡函数进行改进,改单角参数为双角参数,仿真结果表明,遮挡效果有所改善。
Based on the theory of electromagnetic scattering,combined with the frequency characteristics of radar target, used the method of analyzing high frequency scattering principle and the knowledge of space analytic geometry,analyzed the existing Occlusion Function in Target Scatter Model in ISAR Imaging Simulation System.and mended the Occlusion Function on the base of the analysis,changed the single angle parameter to double angle parameters,the result of the simulation indicated that the occluded effect have been improved.
