符号位——作为一种随机过程信息已被应用于地震信号的接收。美国地球系统公司有产品投入生产,其基本理论已于SEG49届年会上发表。本文将对此基本理论略加补充并以明显的数据论证其应用的可能性和局限性,更以美国地球系统公司生产的符号位地震仪——GEOCORⅣ的建立和发展为例,评述该仪器的性能。最后提出如何在地震信号接收中正确应用符号位信息接收理论的设想。
The sign bit - as a kind of random process information has been applied to the reception of seismic signals. The products that American earth system company puts into production, its basic theory has been published at SEG49 annual meeting. This article will supplement this basic theory and demonstrate the possibility and limitation of its application with obvious data. Furthermore, taking the establishment and development of GEOCOR Ⅳ, a symbolic seismograph produced by the United States Earth System Company, as an example, performance. Finally, the author proposes how to correctly apply the sign bit information reception theory in the seismic signal reception.
