一、前言采用静止卫星的国内卫星通信方式,在发生异常灾害时设立临时线路和对孤岛通信等,是有效的一种通信方式。另外,估计这种通信方式可使国内通信线路网可靠性提高,传输容量增大。完成这种国内通信方式任务之一的,可考虑准毫米波车载等形式的移动式地面站,在这种移动站中,必须使天线跟踪卫星。以往,卫星通信用地面站的天线跟踪方法,主要是单脉冲方式,它正在各国地面站中提供实用。但是,在如移动站那样天线口径比较小,以体积小,重量轻为目标的地面站中,特别要求跟踪装置小而轻。 I. INTRODUCTION Domestic satellite communication using geostationary satellites is an effective means of communication in setting up temporary lines and communicating with isolated islands in the event of anomalous disasters. In addition, it is estimated that such a communication mode can improve the reliability of the domestic communication network and increase the transmission capacity. One of the tasks for accomplishing this domestic mode of communication may be to consider a mobile ground station in the form of a semi-millimeter-wave vehicular vehicle in which the antenna must be followed by the satellite. In the past, the antenna tracking method for satellite communications ground stations was mainly single pulse mode, which is providing practicality in various countries’ ground stations. However, in a terrestrial station whose antenna diameter is relatively small, such as a mobile station, and which is small in size and light in weight, the tracking device is particularly required to be small and light.
