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。 Short-wave radio communication usually has a blind spot within 200 km, which restricts its application in short-range mobile communications. In this paper, a short-wave, close-range and blind-free zone communication technology based on a high elevation angle loop antenna is proposed. The feasibility of the technology is analyzed from the aspect of line calculation. The concrete scheme of the technology is given. The specific method. By testing the signal-to-noise ratio (SNR) of the received signal under different working conditions, it is verified that the near-blind no-dead zone technique based on the high-elevation loop antenna has excellent short-wave dead zone elimination performance.
