摘　　要：鉴于通过天线方向图能够直观清晰地衡量机载天线的辐射特性,且基于试飞的测试方法所得方向图更能反映天线在实装环境下的性能,提出了一种基于圆航线试飞的天线方向图测试方法。对圆航线和“梅花瓣”航线下机载天线方向图的测试情况进行了对比分析;介绍了圆航线下天线方向图测试数据的预处理方法,即场强折算和方向角折算方法。测试结果表明:基于圆航线试飞的天线方向图测试方法效率较高,所得方向图的方向性能优良,在作战运用中具有较强的指导作用。The antenna pattern is an important reference to find out the performance base of the airborne antenna,and the pattern obtained by the test flight can better reflect the performance of the antenna in the installation environment.This article proposes a circular route flight method,compares and analyzes the airborne antenna pattern measurement between circular flight route and"cloverleaf"flight route.In this paper,a preprocessing method for the antenna pattern measurement data under circular flight route is introduced,scilicet the method of field intensity convert and direction angle convert is proposed.The experimental results of the antenna pattern measurement confirm that the circular flight route antenna directional pattern testing method is more efficient,and yields more directional information in the test results,and has a more guiding role in combat application.
