摘要
随着电子技术的不断发展,各种无线发射装置的广泛应用,无线接收设备尤其是高灵敏度的雷达都有可能遭遇各种意想不到的电子干扰。通过分析经历过的多起雷达受扰事件,挑选包括气象部门雷达相互间的同频干扰,与军用雷达相互间的同频干扰,微波接力站和民用超高频数传机对天气雷达的干扰等几起具有代表性的典型个例,就其发生现象、检判过程、产生的原因、实际解决办法和最终结果以及带来的相关启示做了一些分析探讨,可为从事技术保障的同行提供有益的借鉴。
Along with the development of electronic technology and extensive application of all kinds of wireless transmitting devices, various unexpected electronic interferences are encountered in wireless receive devices, especially in high sensitive radar. Having experienced several electronic interference events,, some typical cases are selected, such as the co-frequency interference between weather radars, the co-frequency interference between weather radar and military radar, as well as interferences from microwave relay stations and civil UHF transmitters. The electronic interference phenomenon and the detecting process are introduced, and the formation causes and practical solutions are discussed.
