电波环境及微波超视距传播

Radiowave Environment and Microwave Transhorizon Propagation

电波环境是信息化系统和武器装备的重要组成部分,微波超视距传播基于对流层电波环境中的大气超折射(大气波导)和散射机制,可实现数百千米的地基/岸基/船载雷达微波超视距远距离目标探测或无中继微波超视距远距离通信,具有较大的实际应用价值。文章介绍了电波环境的概念和数据要素、对流层大气波导和散射传播的特点以及微波超视距效应评估技术,在此基础上分析了微波超视距雷达探测技术的典型应用场景。

Radiowave environment is an important part of information systems and weapon equipments. Based on the atmosphere refraction and scattering mechanism of radiowave environment, microwave transhorizon propagation can realize the over-the-horizon long-distance target detection of ground-based/shore-based/ship borne radar or non-relay microwave over-the-horizon long-distance communication, which has great practical application values. This paper introduces the concept and data elements of radiowave environment, the characteristics of troposphere atmospheric duct and scattering propagation, and the evaluation technology of microwave over-the-horizon effects. The typical application scenarios of microwave over-the-horizon radar detection technology are analyzed.
