摘要
This paper investigates better time frequency representations of littoral water ambient noise recorded at 30 meter of depth in Indian tropical water. Linear time frequency representations ( TFR) like spectrogram and Continuous Wavelet Transform are compared by combining natural and anthropogenic ambient noise sources from the tropical waters. Underwater ambient noise is represented by appropriate wavelet. Statistical and image quality parameters are used to quantify the quality of these TFRs for passive sonar systems.
