L波段测风雷达故障分析与检修方法

高空气象探测对时间有严格的要求,检修L波段雷达务必突出一个“快”字,好的检修方法是快修的重要手段.本文提出了快速分析与检修雷达故障的方法和措施：从GFE （L）1型测风雷达静态和动态参数的变化入手,以其作为分析、判断故障原因的主要依据,采用信息对比分析和信号关联分析方法,达到快速修复故障雷达的目的.实践证明,结合原理方框图深入分析雷达静态和动态工作特性,可快速确定故障现象、快速分析故障原因、快速判断故障范围、快速排除雷达故障,满足高空气象观测工作的需要.

Analysis on Fault of L-band Windfinding Radar and Method of Fixing

As aerological sounding has strict requirements on time, maintenance of L band radar must be as fast as possible. Repairing quickly enough depends on methods well enough. This paper presents a method to repair L - Band Radar fault fast： Based on static and dynamic parameters of GFE （L）1 Band Wind -find Radar, contrast analysis and signal correlation method can be used to repair radar＇ s fault quickly enough. Practice has proved that according the change of radar static and dynamic parameters, combining with the principle block diagram, the thorough analysis of the static and dynamic job characteristics, this method can make faults judging＂ precise, steady, fast＂, achieving quick and perfect repairing.
