微波超视距雷达大气波导环境

Atmospheric Wave-guide Environment for Microwave Over-the-horizon Radar

针对岸基/舰载微波超视距雷达远距离海上低空或海面目标探测的实际需求,首先对大气波导的直接测量和遥感反演等探测方法进行了分析比较,基于对大气波导形成机制和中尺度数值预报模式的分析,指出了有效预报大气波导需要解决的3个基本问题,最后对微波超视距雷达电波传播模型和评估方法进行了讨论。

Direct measurement and remote sensing inversion methods of atmospheric wave-guide detection methods were analyzed and compared according to the practical requirements of shore or ship-borne microwave over-the-horizon radar for long distance low altitude and surface targets detection over sea.Based on the analysis of atmospheric wave-guide mechanism and mesoscale numerical weather forecast model,three fundamental problems were presented,which should be solved effectively for atmospheric wave-guide forecast.Radiowave propagation models and evaluation methods for microwave over-the-horizon radar were discussed.
