Geoacoustic Characterization Research Based on the Range Domain Interference Spectrum

Coherent structure has been leaded by multipath propagation in a shallow-water environment in the received field,both spatially and temporally.In this paper,range domain interference spectrum extraction cycle is used as a matching physical quantity.On the basis of single homogeneous infinite ocean model,the optimal solution has been searched through the simulated annealing method which established with minimum mean square error cost function,and a seafloor parameters inversion method has been put forward.Simulation results show that the method of inversion obtained parameters can be effectively applied to acoustic field prediction.
