Feature extraction of targets radiated noise and design of targets classifier are key technique of passive sonar target recognition system.
The first part is about the features extraction, including the estimation of source level of the ship-radiated noise and the line extraction of the rotation frequency of propeller noise spectrum.
Analysis and simulation of auditory features extraction of ship-radiated noise
The result indicates that the method is an effective way to extract the modulated information from radiated noise.
Application of principal component analysis to ship-radiated noise classification and recognition
Therefore, development of a technology for the submarine to detect the anti-submarine helicopter by monitoring the helicopter radiated noise in underwater is urgently required.
The low-frequency noise of propeller has constituted the main part of radiated noise of middle or high-speed marine.
Application of adaptive line enhancement on testing the ship-radiated noise
The spectrum of radiated noise from ships consists of a continuous broadband spectrum and a discrete narrow-band line-spectrum.
A separation method of naval ship radiated noise sources using measure data of radiated noise was introduced.
