摘　　要：随着我国民航近些年的快速发展,新疆地区的航空业务量持续走高,为适应远期新疆管制区域内管制业务量增长的保障需求,近年来在新疆地区陆续投运多部空管二次雷达,其中包括SCR-22SS型二次雷达。近期在该型雷达运行保障中出现了雷达数据传输异常情况,通过详细的故障摸排检查,确认属雷达信号时钟同步问题,最终解决了雷达信号传输丢包、错帧的问题。本文针对异常现象及其解决办法进行详细论述。With the rapid development of civil aviation in China in recent years, the aviation business volume in Xinjiang has continued to increase. In order to meet the demand for ensuring the long-term growth of control business volume in the Xinjiang control area, multiple air traffic control secondary radars have been put into operation in Xinjiang in recent years, including the SCR-22 SS secondary radar. Recently abnormal transmissions of radar data occurred in the operation of this type of radar. Through detailed fault diagnosis and inspection, a problem with radar signal clock synchronization was identified, and the problems of radar signal transmission packet loss and frame errors were ultimately solved. This article elaborates on the abnormal phenomena and the solutions.
