本文概略地介绍了符号位地震勘探的原理。首先从统计检测理论出发,深入浅出的阐明,为什么只利用地震信号记录的符号位就可以检测地震信号,然后说明对普通地震资料进行符号位处理的依据和方法。最后以可控震源为例提出用特定的、信号已知的震源,从记录开始就只采用符号位进行地震勘探的设想。 This article gives a brief introduction to the principle of symbolic bit seismic exploration. First of all, based on the theory of statistical detection, it is explained in simple terms why the seismic signal can be detected only by the sign bit recorded by the seismic signal, and then the basis and method of sign bit processing for ordinary seismic data are described. Finally, taking the Vibrator as an example, we propose to use a specific source with a known signal, and only use the sign bit for seismic exploration from the beginning of recording.
