A new type of high-speed multi-channel radar system and data acquisiton is introduced. The controling and the method of key technologies are introduced also. These technologies change the radar' s current situation of which can only control a single channel or two hardware channels. Developing a host that can support 1 to 5 groups of radar antenna, and also can dynamically increase or decrease the number of antenna ff necessary. Each channel can separately set parameter, and they are independently of each other. The USB controller of this design is 68013A chip of CYPRESS company, and using the CPLD as the main control module,this two part constitute the control unit. The PC program is complied by using VC ++ 6.0. The software system's overall communication protocol has also been complied, so a high-speed, convenient, accurate data acquisition system has achieved.%介绍了一种新型基于USB的多通道高速雷达控制、数据采集系统的关键技术及其实现的方法.改变了以往一台主机只能控制单个通道或者两个硬件通道的现状.开发出一台主机可以同时连接1～5组雷达天线,并可以根据需要动态增减.每个通道可以单独进行参数设置和采集控制,各个通道之间互不影响.硬件部分是以CYPRESS公司的68013A芯片为USB控制器,采用CPLD为主要控制模块,共同组成控制单元.使用Visual C++6.0编写上位机控制采集程序,编写了软件系统的总体通信协议,实现了高速、便捷、精确的数据采集系统.
