摘　　要：为实现某型号机载雷达系统功能和性能信号的自动测试,以AT89C52单片机为核心,采用可更换接口适配器,完成雷达显示分机、收发分机和天线分机自动测试台硬件和软件设计,成功解决了待测分机接口不同和待测信号种类繁多、微波信号测试等难题,实现了资源共享和自动测试的目标;采用模块化结构完成雷达自动测试软件设计,与自动测试台硬件配合,实现雷达系统各要求项目的测试及对测试过程的控制;实际应用表明,该自动测试台测试结果100%正确,且运行稳定,具有智能化程度高、操作简便、减少维修检测的人为误差等优点,为雷达使用过程中的维护、故障检测与诊断提供了有效的保障,推广应用前景好,经济效益明显。To automatic test the function and performance of an airborne radar, changeable test adapter is adopted to implement the hard ware and software design of the automatic test set of the antenna, transceiver and indicator of the radar based on AT89C52. Problems such as the different types of interfaces, the various kinds of signals and the test of microwave signal are solved successfully and the objectives of resource sharing and automatic test are realized. The test software is designed by modular structure, and with the help of automatic test set hardware, the required test items of the radar system are experimented and the test process control succeeded. Experiment results show that the automatic test set performs steadily and the results meet the requirements of the airborne radar. The set has the advantages of intelligent, manageable and reducing artificial errors. It provides effective guarantees for radar＇ s maintenance, fault diagnosis and fault detection, and has a wide application prospect with low cost.
