多径效应中雷达反射模型的研究

摘要

Multipath effect is one of the key factors in the design process for radar model to be considered,but there is a difference in multipath effects produced by different radar reflection models. Unforseen influence by multipath effect on radar actual detection is the purpose of scholars' study on the multipath effect. This paper introduces the reasons why the multipath effects produced and the performance effects resulting from mul-tipath effects of two typical radar reflection modes:the spherical reflector model and the slopes reflector mod-el . The corresponding parameter of model structure is designed by MATLAB and the multi-mode cycle simu-lation has been done. The simulation results prove that difference reflection multipath effects need to be han-dled in difference application environment.%多径效应是雷达模型设计过程中需要考虑的关键因素之一，不同雷达反射模型中所产生的多径效应是有差异的。多径效应对雷达实际探测效果产生不可预见的影响是学者们研究多径效应的目的。基于此研究背景，介绍了多径效应产生的原因，并通过2类典型的雷达反射模型-球面反射模型和斜坡反射模型研究多径效应造成的性能影响，通过MATLAB实验设计了相应模型参数结构，并进行了多模式循环仿真，仿真结果证明，不同反射模型中多径效应的效果在不同应用环境中需做相应的处理。
