Sound speed profile and geoacoustic parameters estimation

With the advancement of sonar technology and inverse problem theory, the use of acoustic signals to retrieve the parameters of underwater acoustic environments has received more and more attention. Based on the parabolic equation (PE) solver and genetic algorithm, this paper studied the problem of jointly inverting the water sound speed profile (SSP) and geoacoustic parameters, where the dimension of water SSP was greatly reduced by the EOFs. Numerical experiments show that this method can provide a high accurately retrieved results with noise free case observations, as well as a favorable anti-noise ability for 3dB Gaussian noise case.
