在过去几年中,通过大西洋富田公司(Atlantic Richfield Co)的勘探研究部发展了一种叫做BESS(二进制编码地震系统)的新地震系统。新系统的震源是一组由伪随机二进制代码顺序控制的轻型的、快速引火气爆震源(Dinoseis)爆炸装置,把编码信号传到地下,在译码处理中仅用了接收信号的极性信息(1位数据)。BESS信号的译码操作很简单,它由收到的信号与控制爆炸装置的二进制代码的极性符合对比(相
In the past few years, a new seismic system called BESS (Binary Coded Seismic System) has been developed through the Exploration and Research Division of Atlantic Richfield Co. The source of the new system is a set of light, fast, and detonating Dinoseis explosive devices controlled sequentially by pseudo-random binary code to pass the coded signal down to ground, using only the polarities of the received signal in the decoding process (1 bit data). The decoding operation of the BESS signal is very simple and it is in contrast with the polarity of the binary code that controls the explosive device
