| 摘 要： | 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.

| Abstract: | 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. In this paper, 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 is presented, respectively. |

| Keywords: | specular reflection diffuse scattering mutipath effect Low-Angle radar tracking |
