摘　　要：传统的人工测试方法,存在耗时、精度差、不易扩展等缺点,是制约雷达测试技术发展的瓶颈,急需研制一套雷达通用自动测试系统。通用自动测试系统是在标准的系统总线基础上搭建,辅以专门设计的适配器,可以完成多个分系统的多个模块、插件的测试。自动测试系统识别适配器编码,自动调用不同的测试方案。基于故障树系统的测试项目管理可以分析、诊断被测件故障,并根据故障现象分析故障发生的原因,然后提出诊断的方法,最终实现故障的定位。经过实际应用证明,该系统具有良好的通用性,自动化程度高,真正实现了仪表参数的自动设置、数据自动采集、测试结果自动存储等多项功能。而且,该雷达自动测试系统功能完善、性能稳定,在某出口雷达研制过程和后期维护阶段都发挥了重要作用。Since some shortconmings as time-consuming,poor accuracy and difficult expansion,traditional manual testing method has bottlenecked the rapid development of radar testing technology,so we have to build new ones urgently.Based on standard system bus and specially designed adapter,the general-purpose automatic test system can test diversified modules or plugins of many subsystems.After recognise the adapter ID,automatic test system execute corresponding testing schema automatically.Testing management system can analyse and diagnose the fault of equipment under test（EUT）,trace back to fault causes from fault phenomena.Then,it put forward fault diagnoses method,finally implement fault localization.Through practical application,it has been proved that the system has good versatility,high degree of automation,really implement the instruments parameters automatically set,automatic data acquistion,automatic storage of the test results and many other functions.Furthermore,the radar general-purpose automatic test system show the construction of perfect function,stable performance.The system played an important role on RD process and Maintenance of an exported radar.
