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.
