双基多普勒天气雷达信号采集方法研究

Research on the Collection Method of Bistatic Doppler Weather Radar Signals

介绍了基于工业控制计算机实现的双基地多普勒天气雷达单站接收系统,针对现有系统存在的弱回波检测能力差、旁瓣干扰大等问题,提出采用多组高增益、窄波束、多通道信号采集方案,并利用TCP/IP网络协议,实现雷达信号处理数据的实时传输。

It introduces the single state receiving system of bistatic Doppler weather radar on the basis of indus-try personal computer (IPC),which suggests a collection scheme by means of multi-group,high gain,narrowbeam and multi-channel signals,and achieves the real-time transmission of radar signal processing data usingTCP/IP network protocol,aiming at the problems of poor weak echo detection ability and high sidelobe contami-nation.
