基于FPGA的雷达脉冲采集器设计

Radar Pulse Acquisition System Based on FPGA

介绍一种用于雷达侦察设备的中频信号采集和分析系统,核心是雷达脉冲信号高速采集卡。雷达脉冲信号采集卡采用大规模FPGA芯片实现脉冲捕获以及高速数据流的分配,具有雷达信号中频数据采集、脉冲串捕获、时间同步、数据高速存储和通信功能;通过PCI接口与系统信号处理软件交互数据和控制,能进行雷达信号脉内特征分析及显示,同时还能进行雷达信号全脉冲情报分析,有极高的可靠性和灵活性。

An intermediate frequency analyse system of radar reconnaissance is introduced.And a high-speed radar pulse acquisition card is the key part in the system.The card can capture radar pulses and distribute high speed acquisition data flows with FPGA chip.It can achieve the following functions,i.e.,data acquisition of radar intermediate frequency,capture of pulse series,synchronization of timer,high speed storage and communication with analyse software,and so on.The analysis system is highly reliable and flexible.The signal processing software can implement intrapulse analysis and pulse repetition interval analysis by PCI bus exchanging data and achieve controls with the card.
