摘要
基于记录回放仪项目,此项目采用的采集卡仅具备两个模拟输入通道,无法对雷达视频信号及多个标志位信号进行同步采集,由此设计了接口板,提出单通道采集多路信号的记录回放仪设计方案与实现方法,解决了记录回放仪中单个采集卡对多路信号采集的问题。文中设计的接口板适用于多种型号导航雷达,核心固化,易于升级,可扩展性好,成本低廉。
Recording playback device based project, which capture card is only input channels, not on the radar video signal and a number of flag signals synchro designed the interface board, proposed multi-channel signal acquisition recording y used with two analog nous acquisition, which playback device design and implementation of ways to deal With the record in a single capture card playback device for multi- channel signal acquisition problems. This interface board designed for a variety of models navigation radar, core curing, easy to upgrade, scalability and low cost.
