低角雷达跟踪时的多路径散射模型

Multipath scatting model of Low Angle radar tracking

要提高低角雷达跟踪目标的精度 ,就需要考虑由于地、海表面反射而产生的多径效应的影响。需要弄清产生多径效应的环境和条件 ,建立多径效应的数学模型 ,以便采取合理的方法进行抑制。本文给出了镜反射和漫散射引起的多径效应的代表性模型 ,以及考虑表面粗糙度、遮蔽效应等影响的修正粗糙面漫散射模型。

To improve the tracking precision of low-angle radar, it is necessary to consider mutipath effect caused by reflection of the earth and sea surface. A model of mulipath effect caused by specular reflection and diffuse scattering and a modified roughness diffuse scattering model considering surface roughness and masking effect are presented.
