摘　　要：在雷达系统仿真中雷达天线方向图的设计与实现是重要的一环,较好的雷达天线方向图设计可以有效地提高雷达系统仿真的速度和逼真程度。首先介绍传统的天线方向图原理与实现,但是传统的天线方向图在实现归一化和俯仰角方面有一定的缺陷。针对两个方面的缺陷,对传统雷达天线方向图函数进行了增加和改进,并对方向图函数进行了仿真。通过仿真可以看出,改进型的天线方向图在俯仰和方位两方面表现得更加完善,更逼近于实际雷达天线方向图。The design and realization of radar antenna direction chart are important in simulation of radar system. The good design of radar antenna direction chart can improve the rate and reality of radar system simulation. The traditional antenna direction chart is introduced. The traditional antenna direction has two bugs which are normalization and pitch angle. Because of these bugs,antenna direction chart {unction which is improved on and added. The direction chart function is simulated. The simulation indicates that through the improved antenna direction chart is better in pitching and direction, and also approaches real radar antenna direction chart.
