Abstract

This disclosure proposes a channel wave signal multipath spectrum analysis method and system. Multiple channel wave signals are obtained by transmitting detection signals at different angles, which can achieve the purpose of multi-directional detection of the target geological interface, increase the detection range, and more To reflect the geological information of the formation to be measured, in terms of channel wave signal extraction, a non-orthogonal decomposition method is used to decompose the channel wave signal to decompose each multipath in the channel wave signal, and multiple echo signals are fused to obtain the channel wave signal. The multipath spectrum of the wave signal. This decomposition method has high decomposition precision and is more practical. The decomposed signal can retain as many characteristics of the interface signal as possible, and can express the obtained signal more concisely, thereby improving the signal-to-noise ratio of the signal, reducing the bit error rate of the signal, and improving the accuracy of slot wave detection.

Description

Technical field[0001]The present disclosure relates to the technical field of slot wave exploration, and in particular, it is to involve a slot wave signal multi-diameter spectrum analysis method and system.Background technique[0002]The statement of this section is merely the background technology information related to the present disclosure, and it is not necessarily constituted in prior art.[0003]The elastic wave is in the formation of the formation, and the slot wave signal is formed by the characteristic of the geodetic channel, which is unique to the stratification, unevenness, etc. The multipath signal in the slot wave can be analyzed to obtain geological exploration and obtain the distribution of geological layers. In the coal mine detection, it is possible to detect the fault, column, cavity, etc. of the coal seam, and have an important role in the safety production of coal mines. Each multipath signal in the slot wave signal is mixed together, and it is necessary to take a...
