摘　　要：跨海微波超视距远距离传播深受探测和通信领域的重视,其机制分析和规律观测有重要意义.本文对跨海微波超视距远距离传播的机制和有关原理进行了分析,对2019-09开展的C波段和X波段微波昼间跨海面超视距远距离传播试验进行了研究;利用试验测试记录和期间的气象站风观测数据,对试验期间观测到的C波段不同距离线路和X波段50 km线路上白昼的传播规律和机制做了总结分析.本文结论可供对流层微波超视距远距离传播(大气波导传播和散射传播)研究或应用的系统设计、数据分析和机制研究等参考使用,特别是跨海的试验测试可以直接运用.Long distance microwave propagation transhorizon over sea surface have been paid much attention in detection and communication and the mechanism analysis and characteristics of observation are significant.In this paper,the mechanism and related principle of long distance microwave transhorizon propagation across seawater are analyzed.The test of C-band and X-band microwave propagation over long distance transmission lines far beyond the horizon over sea surface in September,2019 is introduced.The propagation principle and mechanism at daytime of the transmission lines with different distances in C-band and 50 km circuit in X-band are summarized and analyzed based on the signal levels record and the observed winds.The research can be candidate for the system design,data analysis and mechanism investigation of microwave long range trans-the-horizon tropospheric propagation projects,especially for the test across sea surface.
