本文介绍沃希变换和符号位检测在地震勘探中的应用.当前,各种数字地震仪都是把各次采样和各道间数据作为独立的、不相关的信息进行传输和记录,因而传输和记录了大量多余的信息.实际上,各次采样和各道间的数据都密切相关,可以将这些信号的数据进行压缩,以充分应用传输和记录信道,提高地震勘探的效率.目前,统计数学、数学技术和半导体技术的成就,已可以实现在检波器站上将数据压缩;在计算站上也有从压缩的数据中检出有用的信息恢复其本来面貌的能力.这就为研制数据压缩的地震仪创造了条件.
In this paper, the application of Walsh transform and sign bit detection in seismic prospecting is introduced.At present, all kinds of digital seismometers transmit and record each sample and each track as independent and irrelevant information, so the transmission and Recorded a lot of redundant information.In fact, the various samples and the data is closely related to each channel, you can compress the data of these signals in order to make full use of transmission and recording channels to improve seismic exploration efficiency.Currently, Statistics and Statistics , Mathematics, and semiconductor technology have made it possible to compress data at geophone stations; there is also the ability to recover useful information from compressed data at a computing station to restore its original appearance. This has led to the development of data compression Seismograph created the conditions.
