Simulation model of bottom reverberation signals for horizontal bistatic receiving array

In the present work, the bottom reverberation signals model based on ray acoustics theory is developed using unit scattering model. The radius of spatial correlation of bottom scattering coefficient is used to set scattering units. The bottom scattering coefficient is formed with LAMBERT Law. Making use of emulated multi-array-elements data, the relation between characteristics of bottom spatial correlation and sea ambient parameters are analyzed. The emulation result shows that the spatial correlation of bottom reverberation signal for horizontal bistatic receiving array does not change with angle factor of LAMBERT Law and difference of scattering coefficient, instead it increases as correlation radius of bottom scattering coefficient increases.
