随着气象的多样化和极端天气的频繁出现，飞机在飞行时更需要气象雷达的支持

With the diversification of weather and the frequent occurrence of extreme weather, airplanes need the support of weather radar when flying. Weather radars are generally built in sparsely populated open spaces. Damage to it in various weather and natural aging of parts and components will affect the performance of weather radars and normal operations. <br>This article takes civil aviation weather radar display failure as an example, introduces the connotation of aircraft weather radar, its application in the civil aviation safety center, and the analysis of the basic composition and principle of weather radar, from antenna group failure, radar display not display, weather radar switch circuit failure , Weather radar target distortion, etc. The common faults of weather radars are analyzed, and the measures for troubleshooting and maintenance of weather radar faults are effectively proposed. It is hoped that the research can provide suggestions for the safe flight of civil aviation aircraft and eliminate the faults of weather radars. Make your own point of view. <br><br>Keywords: weather radar, display failure, analysis and elimination

With the diversification of weather and the frequent appearance of extreme weather, aircraft need more support from weather radar when flying. Weather radar is generally established in a sparsely populated open space, all kinds of weather damage and the natural aging of spare parts will affect the performance of weather radar and normal operations.<br>Taking civil aviation weather radar display failure as an example, this paper analyzes the common failure of meteorological radar from the aspects of antenna group failure, radar display failure, weather radar switch line fault, meteorological radar target distortion, etc. by introducing the connotation of aircraft weather radar, the application of civil aviation safety center, and the analysis of the basic composition and principle of meteorological radar, so as to effectively put forward the measures of weather radar fault elimination and maintenance, hoping to provide suggestions for the safe flight of civil aviation aircraft. Make your own point for weather radar troubleshooting.<br><br>Keywords: weather radar, display fault, analysis and elimination

With the diversification of weather and the frequent occurrence of extreme weather, aircraft need the support of weather radar when flying. Weather radar is generally built in the sparsely populated open-air places. The destruction of weather and the natural aging of parts will affect the performance and normal operation of weather radar.<br>Taking the display fault of civil aviation weather radar as an example, this paper introduces the connotation of aircraft weather radar, its application in Civil Aviation Safety Center, and the analysis of the basic composition and principle of weather radar, and analyzes the common faults of weather radar from several aspects, such as antenna group fault, radar display failure, weather radar switch circuit fault, weather radar target distortion, so as to effectively solve the problem Put forward the weather radar troubleshooting and maintenance measures, hope to provide suggestions for the safe flight of civil aviation aircraft, put forward their own views for weather radar troubleshooting.<br>Key words: weather radar, display failure, analysis and troubleshooting<br>
