一种基于高仰角天线的无盲区短波通信技术及其实现

短波无线电通信在200公里范围内通常存在着盲区,这一特点制约了其在近距机动通信中的应用。文中提出了一种基于高仰角环型天线的短波近距无盲区通信技术,从线路计算方面分析了技术实现的可行性,并给出了技术实现的具体方案,对高仰角环型天线给出了具体实现方法。通过对系统模型在不同工作条件下接收信号的信噪比测试,验证了文中的基于高仰角环型天线的通信近距无盲区技术具有优良的短波盲区消除性能。

A HF No-blind Zone Communication Technology Based on High Elevation Angle Antenna and Its Implementation

HF radio communication has a significant communication blind zone in the range of 200 kilometers usually.This disadvantage restricts its application in the near range tactical mobile communication.This paper presents a kind of no-blind zone HF communication technology based on the high elevation angle circularity antenna.The feasibility of technology implementation is validated by the calculation of communication line.The technology implementation scheme of the no-blind zone communication system is given.The material implementation method of the high elevation angle circularity antenna is given also. After testing the signal-to-noise ratio of the received signals in multifarious work conditions,we can obtain a conclusion.The no-blind zone HF communication technology based on the high elevation angle circularity antenna has excellent eliminating HF blind zone performance.
