大气波导效应及其对低空探测的影响分析

对于低空搜索雷达来说,希望能尽早准确地判知低空威胁目标,但在出现大气波导效应时,雷达探测性能往往会受其影响;从大气波导效应的成因、类型以及在我国的分布情况出发,分析了大气波导效应对低空搜索雷达正常工作的影响,初步提出了在大气波导情况下改善和提高雷达低空检测性能的技术措施。

Atmospheric Duct and its Effect on Performance of Low Altitude Detection

For low altitude searching radar, it is expected to accurately detect low altitude threatening targets as soon as possible. But when the Atmosphere Duct occurs, the radar detection performance will be generally influenced. This paper reviews the causes and types of "Duct" and its distribution in our country, analyses its effect on radar performance of low altitude detection, and presents technical measures for improving and enhancing low altitude detection performance of radar in "duct" environment.
