A sound source position estimation method, readable storage medium and computer equipment

Abstract

The present disclosure provides a method for estimating the position of a sound source, a readable storage medium, and computer equipment. The single-vector hydrophone receives a multi-channel signal from a sound source in the ocean; through the joint sliding of the fixed window-dynamic window, the received The multi-channel signal is fused into an instantaneous single-channel sound intensity signal, and is divided into signal segments containing sufficient information. On the premise of ensuring the amount of information, the amount of data is reduced and the calculation speed is improved; the maximum expectation algorithm is used for self-complementation of the signal. At the same time, by expanding the distance between the signal segments, the resolution between the signal segments is improved, and to a certain extent, the information lost in the previous interception is supplemented; the sound source position is determined by using the equal-length signal after self-complementation through the cyclic neural network. estimation; the sound source estimation method described in the present disclosure only needs to use a single-vector hydrophone to collect signals, which not only simplifies the difficulty of arrangement and the cost of use, but also expands the scope of application.

Description

technical field [0001] The present disclosure relates to the technical field of sound source position estimation, and in particular to a sound source position estimation method, a readable storage medium and computer equipment. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the rapid and continuous growth of our country's economy, the population is also increasing, and people's demand for resources and consumption levels have also increased significantly. For the limited resources on land, people are also developing and utilizing them as much as possible, and at the same time they will also face resource shortages. Therefore, we must research and develop new ones on the basis of maximizing the use of existing resources. fields and new resources. The ocean area accounts for more than 70% of the earth's surface area, so it is very ...

Problems solved by technology

[0005] The inventors of the present disclosure found in the research that at present, single-vector hydrophones are mostly used to estimate the azimuth and pitch angle of the target, while the judgment of the distance of the target position needs to use the vector hydrophone array for cross estimation. This is because the single-vector hydrophone Due to the inherent defect of the earphone for insufficient distance resolution; and in the actual engineering application of the single-vector hydrophone, on the one hand, due to the limitation of the process conditions, the actual parameters are difficult to meet the requirements of the ideal electro-acoustic parameter characteristics, which restricts its azimuth estimation accuracy. On the one hand, it is susceptible to uncertain changes in attitude due to the influence of the environment, which further affects the acquisition of the true orientation of the target. These reasons lead to the insufficient application of single-vector hydrophones in target position estimation
