摘　　要：中频信号数字化处理技术是雷达数字化的关键,介绍了一种基于A/D和DSP的中频信号采集技术,给出了数据采集系统的原理和框图,并对AD与DSP的接口电路进行了分析。实际设计表明,用FIFO作为两者之间的接口可以产生很好的效果,DSP通过CPLD对采样时序进行控制,增加了系统的灵活性,为雷达中频信号数字化处理提供了一个可行的方法。The intermediate frequency signal digitize processing technology is the key of radar digitize, and introduces one kind of data acquisition technology of intermediate frequency signal based on a high speed of A/D and DSP,and displayes the principle and the block diagram of data acquisition system,and analyzes the interface circuit to A/D and DSP. The real design indicates that can give rise to very good effect with FIFO as the interface between both,DSP controls by way of CPLD to orde＇r during sampling,and increases the flexibility of system, and provides a feasible method for the radar intermediate frequency signal digitize.
