| 摘 要： | 雷达在低角跟踪目标时,必然存在地面或海面反射,从而形成多径干涉效应,在此情况下的雷达电波的到达角就会发生变化,从而影响雷达的测量精度.本文首先从雷达接收信号出发,推导了雷达参数与达到角的关系,然后给出了用最大似然法估算到达角的方法,并且对它进行了仿真计算.

| Abstract: | For the Low-Angle radar,radio wave arrived angle will change due to multipath interference effect caused by the reflection of the earth and sea surface. The change will affect the measure precision of radar. In this paper,a relation of radar parameter and arrived angle is firstly deduced by using the received signal of radar,then a scheme of arrived angle estimation is presented by employed the maximum likelihood method. Finally,the simulation results are shown. |
