摘　　要：天线方向图是雷达的一项重要性能指标,方向图的自动测试在雷达性能测试中占有极其重要的位置。本文分析天线方向图测试原理的基础上,介绍了一种雷达天线方向图自动测试系统,该系统在信号录取、角度录取、数据处理、方向图绘制方面全部实现了自动化,具有精度高、测量速度快、性能稳定、价格低廉的特点。本文阐述了该方向图自动测试系统的电路组成及信号采集与数据处理原理。最后给出了对某圆锥扫描雷达天线方向图的测量结果。The antenna pattern is an important performance parameter of radar, and its automatic measurement is possessed of an important position in radar performance measurement. Based on the principle of antenna pattern automatic measurement, the paper introduces an automatic measurement system of radar antenna pattern. The system, whose signal extraction, angle extraction, data processing and pattern plotting are automatic, has the quality o[ high accuracy, high testing velocity, high reliability and low price. The hardware of this system and the principle of signal extraction and data processing are analyzed. In the end, the testing result of one conical scan radar antenna pattern is given.
