摘　　要：为了在线检测、存储、处理多种形式和多种频率的核信号,采用硬件、软件相结合的方式构造出一种基于超高速数据采集卡(3通道、1 GS/s采样率、1 ns同步精度)、利用PC平台的多适性核信号处理与分析系统。当来源核信号为脉冲形式时,采集按时间数字转换方式记录信号;当来源信号为连续形式时,采集按模拟数字转换方式记录信号。设计了对应于不同信号形式的处理流程和算法,有效得到了核信号随机过程的相关函数、功率谱估计等主要结果。To on-line detect, store and process nuclear signals with multiple forms and multiple frequencies, a compatible processing and analyzing system for nuclear signals based on ultrahigh-speed data acquisition card was constructed. When the source signal is at pulse form, the system records signal with the mode of time-digital-converting. When source signal is at continuous form, the system records signal with the mode of analog-digital-converting. The processing procedures and algorithms were designed for various signal forms. The results for nuclear random process such as correlation function and power spectrum were effectively obtained.
