dc.description.abstract	Remote sediment classification through acoustic methods is of great interest for a few years. The attenuation coefficient of the transmitted wave is an important feature to characterize physical sediment layers properties. Hence, an improved spectral ratio method for the estimation of the chirp sonar signal attenuation is proposed in the paper. A new time-frequency based on technique to compute the least square line as outlaned. Finally, the method is tested on synthetic data and some results are discussed.
