A Study on the Technologies of Ultrahigh-speed Data Acquisition and Signal Processing of Ultrawide-band Radar

Ultrawide-band radars (UWBR) are of very high resolution and have become a new tool of detecting targets. The technologies of high-speed data acquisition and processing of ultrawide-band signals are the key technologies for ultrawide-band radars. A project of ultrahigh-speed, real-time, and direct RF acquisition is put forward in this paper. Pulse compression as a way of processing of ultrawide-band signals is studied. Experiments show that the high-speed data acquisition system may implement the high speed, high accuracy and real-time stable sampling of the ultrawide-band radar signals, and that the algorithm of pulse compression is actually feasible
