Synchronous Control System Design of Hybrid Sky-Surface Wave Radar Network
摘要
Abstract
High frequency hybrid sky-surface wave radar network is designed to extract sea surface state parameters such as sea current and wind speed.It works by transmitting both sky wave and ground wave then receiving ground waves,so this radar network has the feature of wide coved area,abundant backward wave information and so on.Since the transmitting stations and the receiving stations are separated,there needs a perfect synchronization system between the separated receivers and transmitters,as well as among multiple receiving stations,which involves time synchronization,frequency synchronization and phase syn-chronization.In order to satisfy the requirement of the radar network,a scheme of synchronous control sys-tem is presented which includes external synchronization sub-system based on GPS and internal synchroniza-tion sub-system based on FPGA.The scheme solves the problem of synchronization for hybrid sky-surface wave radar.The experimental results prove the validity of the proposed scheme.关键词
