Based On Muzzle Velocity Radar, High-speed Data Acquisition System Design And Implementation

In this paper, we describe the research and realization of the high-speed data acquisition system applied in initial velocity radar. The sampling rate can reach 40MSPS, and the resolution is 12 bits. The acquisition speed that the system provides can be altered.The paper deals with in detail the specific structure and function of the radar data acquisition system, and introduces its method of realization and applied technology. It implements filter groups design, wide range linear automatic gain control design, and the programmed logic device design based on VHDL, and discuss their application in initial radar system in details.
