摘　　要：利用出现概率较高的蒸发波导实现舰船雷达、通信等电子系统进行超视距探测和信号传播是目前的研究热点。为了检验蒸发波导的出现与雷达超视距探测的相互关系,采用精度高、反应速度快的大气波导测试仪在海面上空进行蒸发波导的实际测量,同时也利用海岸上的雷达进行探测。实测结果表明,当雷达的工作区域出现蒸发波导时,雷达能够实现超视距探测,且随着蒸发波导的强度不同,雷达探测信号的强度也相应地发生改变,证明了蒸发波导的实际测量与雷达信号实现超视距传播的一致性。The use of the evaporation duct which appears in a higher probability by ship radar and communication electronic systems to realize the over-the-horizon detection and signal transmission has become the current hotspot. In order to test the correlation of the emergence of evaporation duct and radar＇s over-the-horizon detection, atmospheric duct tester is used which has high precision as well as fast response to measure the evaporation duct in the sky above the sea, at the same time, the radar which is fixed on the coast is used to carry out the detection. The actual results show that when the evaporation duct appears in the radar＇s work area, radar would be able to achieve the over-the-horizon detection, and the strength of the radar＇s signal is different with the change of the intensity of the evaporation duct. The consistency about the evaporation duct＇s actual measure and the radar signals＇ over-the-horizon propagation is proved.
