摘　　要：雷达电源是保证雷达安全运行的关键,当电源出现故障时,为了及时报警以便操作人员检修或自动切换到备用电源,保证雷达的正常工作。在分析了相控阵雷达阵面电源的特点以及传统雷达电源保护电路基础上,设计了简单实用的雷达电源保护电路,实现了雷达一次电源故障中的过、欠压保护和二次电源缺相保护。经过实验,该电源保护电路具有抗干扰能力强、灵敏度高等特点,具有一定的实际应用价值。Radar power supply is a key to guarantee the radar safe operation. In order to guarantee the normal operation of radar, the operators should be informed to make power overhaul or automatically switch to the standby power supply when some- thing is wrong with the radar power supply. A simple and practical radar protection circuit was designed on the basis of analy- zing feature of phased array radar wavefront power and traditional power protection circuit, and the over-voltage protection and secondary power supply phase protection were realized. The experimental results shows that this power supply protection circuit oossesses strong anti-iamming capability and high sensitivity, and has a certain practical value.
