Abstract

The embodiment of the invention discloses an underwater glider-based underwater acoustic signal processing method. The method comprises the following steps: acquiring an underwater acoustic signal; performing digital quantization on the underwater acoustic signal, and converting quantized data into underwater acoustic time domain data; performing calculation processing based on the obtained underwater sound time domain data to obtain corresponding result data; the result data comprises an environmental noise total noise level, an environmental noise spectrum level, sound pulse and abnormal noise reconnaissance information, target detection information, target tracking information, tracking target feature analysis information and target discrimination information; the processing result is sent to a far-end shore control system in a satellite communication interaction mode, so that the control of the shore control system on the underwater glider and the secondary judgment of a detection target are realized; the underwater acoustic signal processing method has the beneficial effects that various different types of result data are obtained by processing the acquired underwater acoustic signal, various functions are realized, and the application width and depth are improved.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic detection, in particular to an underwater glider-based underwater acoustic signal processing method. Background technique [0002] At present, in the field of underwater acoustic target detection, most of the collected underwater acoustic signals are obtained by means of boats. Because it is difficult to reduce the self-noise of the platform and it is difficult to deploy in arbitrary sea areas and be on duty for a long time, the acquired signals are not accurate. Not ideal; at the same time, in the process of signal processing, the signal is usually only converted and processed conventionally, and the obtained signal is not further applied, resulting in the defects of a single type of output information and a shallow application depth. Contents of the invention [0003] In view of the technical defects in the prior art, the embodiment of the present invention provides an underwater g...
