摘　　要：方向图是雷达的关键指标,其性能的好坏直接关系到雷达的跟踪性能。如何快捷准确地对其进行测试一直是使用者所追求的目标。结合现有船载测控雷达方向图手动测试方案,研究了基于LabView的雷达天线方向图自动测试系统。充分利用现有的仪器设备,采用虚拟仪器技术的通用接口总线(GPIB)及串行接口方案,通过仪器控制的方式实现天线方向图的快速测试,有效提高了雷达方向图的测试效率。工程实践证明该方法测试高效,测试结果准确。Pattern is a key specification of radar,and its performance is directly related to the tracking performance of radar.The rapid and accurate measurement of pattern has always been pursued by the user.In the paper,an automatic measurement system of radar antenna pattern based on LabView is studied combining with the existing test schemes of ship-borne TTC radar.Making full use of the existing instruments,the rapid measurement of antenna pattern is realized through the technology of GPIB and serial interface scheme.Engineering applications prove the accuracy and efficiency of the measurement method.
