Ship acoustic feature intelligent active control method

Abstract

The invention aims to provide a ship acoustic feature intelligent active control method. According to the control method, a perception sensor is used for detecting acoustic and environmental information such as noise signals, pressure and temperature nearby a ship body under the water surface; an acoustic analysis and feature extraction module is used for extracting required radiation noise signals and acoustic situation information nearby the ship body; a control module generates signals at specific frequency and amplitude through an adaptive control algorithm according to the acoustic features and the acoustic situation information and finally realizes control over the acoustic features through a driving module and a transducer. Through the ship acoustic feature intelligent active control method, the voice print features of a ship can be changed to realize acoustic false camouflage for cheating and confusing the opposite side; moreover, noise nearby the ship body under the water surface can be actively offset when necessary to cut down acoustic feature signals of the ship body and conceal itself to achieve intelligent acoustic stealth. Thus, the intelligent active control and acoustic stealth performance of the ship can be improved.

Description

technical field [0001] The invention relates to a ship control method, in particular to a ship acoustic active control method. Background technique [0002] With the development of underwater sonar detection technology, the detection capability of sonar continues to develop, and the detection frequency band of corresponding sonar is also extended to low frequencies. Compared with traditional control technology, active control technology is used to suppress and reduce the acoustic characteristics of ships and improve the acoustic stealth performance of ships because it can effectively control low-frequency noise. However, under the background of continuous development of underwater acoustic detection, the existing control methods cannot meet the camouflage requirements of ship acoustic concealment and false detection, and it is difficult to effectively cope with the increasingly severe underwater detection requirements. Contents of the invention [0003] The purpose of the...
