说明：  对流层大气波导，可以使电波在较小的衰减下实现超视距传播，从而对无线电电子系统的运作产生严重的影响。对于通讯电路，它使系统间的相互干扰题目变得复杂；对于探测系统，产生的则是雷达空洞、超视距探测等题目。因此开展大气波导环境中电波传播特性及其应用的探究具有重大的理论意义和军事价值。 (Tropospheric waveguide, can make waves in the smaller attenuation achieve-the-horizon communication, and thus the operation of radio-electronic systems have a serious impact. For the communications circuits, which allows the mutual interference between systems has become a complex subject for the detection system is generated by the radar empty-the-horizon detection and other topics. Therefore, to carry out atmospheric environment of radio wave propagation characteristics of waveguides and its application to explore the theoretical significance and of great military value.)
