Abstract : The five topics initiated under this contract involve: (1) study of the multidimensional matched filter pulse analysis method and extension to include multiple receivers; (2) modification of the stochastic parabolic equation (PE) codes to include random rough surface scattering; (3) study of the probability distribution of acoustic intensity and extension of our one dimensional distribution to two dimensions; (4) merging of a fully nonlinear internal wave numerical model with the numerical methods based upon the parabolic equation for ocean acoustic propagation; and (5) initiation of source localization studies using the acoustic travel times measured during the AIWEX Acoustic Transmission Experiment (AATE).
