Acoustic Data Assimilation: Concepts and Examples,oustic predictions with higher resolution and better accuracy, compared to those only using the observation data or the physics model. In this paper, we discuss the concepts and framework required to develop the coupled physics-acoustical data assimilation schemes, and review some typical ADA system

Inference of Sound Attenuation in Marine Sediments from Modal Dispersion in Shallow Water,xis transformation that transforms the original time-frequency relationship of the modes to a new domain in which the modes are approximately tonal and are well resolved. This paper shows that the inversion can be carried out directly in the time-warped domain, and extends the work to estimate low-frequency seabed attenuation.

Measurements of Ultrasound Attenuation of Suspended Particles with Various Size Distributions,cted using 5 and 7.5?MHz acoustic signals, for which several suspended sediment samples with different size distributions and concentrations were utilized. Measurement results are presented here and their comparisons to the model predictions are also discussed.

Target Motion Parameter Estimation for LOFARgrams Based on Waveguide Invariants,for calculating the waveguide invariant (WI) target course angle, velocity and range from the LOFARgram are derived. Then, the method is employed to process the LOFARgrams which are obtained from an acoustic toolbox simulation. The parameters estimation results show the validity of the method.
