CINRAD/S RDA定标常见问题分析

结合中国新一代天气雷达S波段A、B型和C波段B型（CINRAD/SA、SB、CB）的雷达数据采集(RDA: Radar Data Acquisition)部分的报警信息、性能参数、适配数据、接收机和发射机的电路框图及对雷达设备的维修经验，系统地分析了CINRAD/SA、SB和CB的RDA定标和检查中可能出现的各种报警并给出对策。分析中广泛征求了资深专家们的建议、查阅了源程序，甚至不惜临时改变某个最小可替换单元的适配参数或工作状态等手段，通过改变RDA中的雷达性能参数使产生对应报警信息来验证分析结论。旨在为各级雷达设备技术保障人员在RDA的设备维护中提供参考指南。

Analysis of Alarm Messages in CINRAD/S RDA Calibration

A systematical analysis is made of various possible alarm messages appeared during the calibration and check of CINRAD/SA, SB, CB RDA (radar data acquisition), in combination with CINRAD/SA, SB, CB RDA (radar data acquisition) alarm messages, technical specifications, capability parameters, adaptation data, and circuit block diagrams of the receiver and transmitter, and the corresponding countermeasures are presented. During the analysis, the opinions of experienced technicians and the source codes are considered, and even the parameters and working status of a certain least replaceable unit are modified temporarily. The alarm messages resulted from modifying the RDA capability parameters are used to check the analysis conclusions. The findings can be used as references for the technical maintenance personnel of RDA equipment.
