摘　　要：为采集超大数据量的、机载雷达获取的宽带中频信号,提出一种高速数据采集方案。在改进现今出现的一些高速数据采集方案基础上,对硬件电路设计以及系统联机调试方面应注意的问题进行了详细阐述。将采集存储的数据回传到上位机并通过MATLAB仿真,反复验证表明,该方案有效地解决了超大数据量的高速传输以及传输过程中信号完整性问题。因此,该高速数据采集平台具体精度高,可扩展性较强的特点以及很好的工程使用价值。To sample wideband IF signal with large amounts of data from an airborne radar, a high-speed data ac- quisition program is presented. On basis of improving some of current high-speed data acquisition program, the problems which should be noted in designing hardware circuit and system online debugging are depicted in detail. By transmitting the sampled and stored data back to the host computer to simulate with MATLAB, the results verify that the program can effectively solve the problems of high-speed transmission of the large amount of data and the signal integrity in transmission. So, the high-speed data sampling platform is featured with characteristics like high precision, strong sealability and can be applicable in engineering.
