The channel number of shallow seismic prospecting is not large, so we can use a logic system to control a signal A/D to collecting data channel by channel.
浅层地震勘探数据记录道数少,采用单个A/D模数转换器件通过逻辑系统控制实现少量地震道的多路循环分时采集,在满足采样定理所需采样频率和不增加地震信号初至系统误差的前提下,可以以较少的硬件成本实现浅层地震信号的有效采集,这种采集方式我们称之为有效拟同步采集;通过实践证明了其采集方式的有效性。
