作为实现国内卫星通信的第一步,在日本的横须贺市建立了卫星通信实验站。本卫星通信实验站除了使用微波(4,6千兆赫)频带外,还使用亚毫米波(18,26千兆赫)频带,与设在远离实验站约5.7公里的模拟卫星组合一起,可以进行宽频带通信实验。本文叙述实验站设备中通信设备的发射系统,接收系统与模拟卫星往返系统等的传输特性(振幅特性,延迟特性)及试验系统的传输特性。单个装置和馈电系统的理论特性与实测特性基本上是一致的,如予测那样,得到宽频带的特性。
As the first step towards domestic satellite communications, a satellite communications experiment station was established in Yokosuka, Japan. In addition to using the microwave (4,6 GHz) band, the satellite communications experimental station also uses sub-millimeter wave (18,26 GHz) frequency bands, in combination with analog satellites located approximately 5.7 km away from the experimental station, allowing broadband With communication experiment. This article describes the transmission characteristics (amplitude characteristics, delay characteristics) and the transmission characteristics of the test system of the transmitting equipment, receiving equipment and the simulation satellite shuttle system of communication equipment in the laboratory equipment. The theoretical and measured characteristics of a single unit and feed system are basically the same, as measured, resulting in a wide band of characteristics.
