中文摘要: 根据CIRAD/SA、SB雷达接收机特点,论述了回波强度定标相关的接收机测试通道、信号主通道以及发射机测试信号流程。根据多年天气雷达技术保障经验,详细论述了回波强度定标故障的诊断分析方法,总结出回波强度定标故障诊断流程,并列举了根据诊断分析方法和诊断流程,排除了由接收机测试通道、信号主通道、发射机射频泄露信号引起的回波强度定标故障的三个典型个例。体现了故障诊断流程在新一代天气雷达技术保障的重要作用,为新一代天气雷达技术保障提供借鉴。
Abstract:According to the characteristics of CINRAD / SA, SB radar receiver, this article discusses the process of the receiver test channel, the signal main channel and transmitter test signal, which is related to the echo intensity calibration. Based on years of experience in weather radar technology security, this artilce discusses in detail the fault diagnosis method of echo intensity calibration, summarizes the fault diagnosis process of echo intensity calibration, and lists three examples in which the above falut diagnosis and solution are used to exclude the fault resulting from the receiver test channel, the signal main channel and the RF leakage signal of transmitter.This articles explains the importance of the fault diagnosis in CINRAD technology support and guarantee and makes some advices about it.
