Abstract

The invention belongs to the technical field of signals, and particularly discloses an underwater acoustic signal processing device which comprises a device body, a protection fixing component, a processing mechanism, an underwater acoustic collecting mechanism and a balance weight fixing groove, the bottom of the device body is fixedly connected with the underwater acoustic collecting mechanism, and the top of the underwater acoustic collecting mechanism is connected with the bottom of the device body. The middle part of the device body is fixedly connected with a treatment mechanism, the top and the bottom of the treatment mechanism are connected with the middle part of the device body, and the treatment mechanism can filter the collected water acoustic and also can adjust the depth of the device body penetrating into water so that the water acoustic intensity collected by the device is conveniently changed; the foam layer on a floating block can float on the water surface, so that the floating block can support and float the device body on the water surface, the collected water acoustic is filtered through the rubber plate and the metal plate on the filtering partition plate, other clutters are prevented from occurring when the device collects the water acoustic, and the filtering accuracy of the water acoustic signal is effectively improved.

Description

technical field [0001] The invention belongs to the field of signal technology, in particular to an underwater acoustic signal processing device. Background technique [0002] With the development of science and technology, there are more and more underwater detection activities, so signal processing is becoming more and more important. Clutter or vibration will affect the signal. How to filter the clutter is an urgent problem to be solved. [0003] The existing underwater acoustic signal processing device has low filtration efficiency and poor processing effect, and cannot isolate and filter clutter or vibration. Moreover, the existing underwater acoustic signal processing device does not have a water entry depth adjustment component, so the effect of underwater sound collection is poor, and the device The stability of suspension on the water surface is poor, and it is easy to interrupt the collection and processing of underwater sound by the device. There are still defects...
