発明の名称 (英語) SIGNAL PROCESSING SYSTEM, SIGNAL PROCESSING METHOD, SIGNAL PROCESSING DEVICE, AND PROGRAM
発明の概要(英語) N (where N is an integer at least equal to 1) vibrators 1 send seismic waves into a medium. A receiver 2 receives a combined wave comprising the seismic waves that have been sent by each of the N vibrators 1 and have propagated through the medium. A corrected data generating unit 35 cuts data of a predetermined length D from the end of time-series data of the combined wave received by the receiver 2, and adds said data to the time-series data up to the predetermined length D from the beginning of the time-series data, to generate corrected time-series data. A correlation calculating unit 36 calculates data indicating correlations between each of the N seismic waves sent respectively by the N vibrators 1, and the corrected time-series data.
従来技術、競合技術の概要(英語) BACKGROUND ART
Ground survey, and the existing structure in the investigation of internal injury, in the medium of the investigation does not destroy the characteristics of the medium as a nondestructive measurement is being performed. To Patent Document 1, a plurality of the focal and detector placed such that the medium, the signals transmitted from these the focal at the receiver by receiving and analyzing, a method for measuring a characteristic of the medium is disclosed. In this method, a different pattern of each detector the focal signal based on the pseudo random code sent to the seismic waves, in the receiver, the focal surface of the vibration transmitted from a plurality of wave multiplexing synthetic seismic wave is received. The seismic wave generator is sent from the focal and a receiver of a correlation between the received composite seismic wave is used, information relating to a particular vibration wave are separated.
Such an approach, a plurality of locations at the same time after receiving a signal that is transmitted to be discriminated in the art. In particular, a plurality of continuous reception of the transmission signal is transmitted after the addition processing of the cycle, is a technique known as a so-called stacking, theoretically excellent correlation can be obtained. This technique is the measurement time is required for a long time.
