设备简介

　　高频地波雷达利用短波(3-30MHz)在导电海洋表面绕射传播衰减小的特点，采用垂直极化天线辐射电波，利用海洋表面对高频电磁波的一阶散射和二阶散射机制，可以从雷达回波中提取风场、浪场、流场等海况信息，实现对海洋环境超大范围、高精度和全天候的实时监测。

　　该雷达系统由远端站高频地波雷达系统和中心站合成系统组成，其中高频地波雷达系统远端站包括信号主机、发射机、发射天线、接收天线、辅助系统组成。

　　Product Details

　　This high frequency surface wave radar is equipped with vertical and polarized antenna to send out electromagnetic waves. Shortwaves (3-30MHz) experiences slow decay, and by leveraging the first and second-order scattering of high frequency electromagnetic waves at the ocean surface, the system can extract significant amount of sea data that includes wind field, wave field, and flow field to achieve all weather precision monitoring over an extremely wide range.

　　This radar system combines a remote high frequency surface wave radar station and a central integration unit. The remote station contains signal host, transmitter, reception unit and other auxiliary systems.

　　主要功能

　　测量海洋表面的流场的流速与流向
