Analysis on Key Technologies of K-band FH-TDD MW Equipment

为了满足我国紧跟国外微波通信发展的要求,采用时分双工工作方式、跳频抗干扰体制的微波通信机的研制非常必要。K频段FH-TDD微波机是典型的微波视距通信系统,主要用于中/短距离的"点对点"无线链接。能满足在野战环境下对中小容量微波系统的需求。采用时分双工工作方式,简化设备方案及成本,提高频谱资源利用率;采用高频段、高速率跳频(高跳速,高增益)技术,系统具有很高的抗干扰,抗截获能力。本文通过K频段微波设备的总体设计,着重论述K频段FH-TDD微波通信的时分双工控制、跳频控制和跳频同步等关键技术。

In order to meet China requirements of keeping up with the foreign microwave communication development, it is extraordinarily neeessary to develop microwave communication transceiver adopting TDD operation mode and frequency hopping anti-jamming method. K-band FH-TDD microwave transceiver is a typical microwave LOS communication system which is used for medium/short distance point-to-point wireless link and satisfies the requirements of medium/small capacity microwave system in field condition. By adopting TDD operation mode, it simplifies the equipment scheme and cost, and improves the utilization of spectrum resource. By adopting high speed frequency hopping technology （high speed, high gain）, it increases the ability of anti-jamming and anti-interception. According to the overall design of K-band microwave equipments,the key technologies are studied mainly, such as TDD control, FH control and FH synchronization of K-band FH-TDD microwave communication.
