一款民用导航雷达采集卡的设计与实现

Design and Realization of a Commercial Navigation Radar Acquisition Card

文章简单介绍民用导航雷达的特点和雷达显示终端发展方向,详细描述了一款雷达采集卡的设计方案。该采集卡接收收发机的视频、脉冲、控制信号且作相应处理后,归一化为信息包的形式发送给显示软件,并接收显示软件的各种指令,编码后经串口发送至收发机。采集卡采用模块化的设计,大部分功能由现场可编程门阵列(FPGA)器件内的程序实现,将硬件模块一定程度的软件化,能够缩短开发周期,降低成本,符合民用导航雷达的特点,是实现信息化终端的基础。

The article brieiiy presents cnaracter^u~ trend of display unit. It describes scheme, hardware design, software design and proof techniques of one radar acquisition card. The card receives and processes video, pulses and control signals from transceiver. It packs all the information to the display software. It also receives commands from display software and encodes them to transceiver. The card utilizes FPGA program to realize converting hardware to software. The card is designed modularly, simply and low cost. It coincides with the characteristics of commercial navigation radar and realizes the informatization of radar display terminal.
