摘要
主要研究散射通信车载站天线快速自动对准技术与实现。针对衰落信道的时变特性,提出了散射通信天线快速自动对准的算法研究及实现方法。在通信工程中得以实现的散射通信天线快速自动对准不需在通信设备中另外增加任何硬件设备的前提下即可实现。该设计方案简单有效、经济实用。对配备该技术的散射通信车载站进行了多次外场试验验证,均取得了良好的效果,受到用户好评。
Fast and automatic alignment technology of antennas in the vehicular stations and its realization are mainly studied in this paper. For the time-varying fading channel, the algorithm research of fast and automatic aligmnent of antennas in troposcatter communications and the way of its realization are presented. The technique is applied perfectly in the communication system without additional hardware equipment and it also has the advantages of simpleness, economy and efficiency. Through many field experimentations, all the troposcatter vehicular stations with the technique of the fast and automatic alignment work very well. And they have been highly reputed by users.
