Impact of uncertain environmental knowledge on the shallow-water transfer function
Gingras, Donald F. (NATO. SACLANTCEN, 1992/12)It is assumed that the acoustic channel can be modeled as a linear time-invariant space-variant filter. In this case, from linear systems theory, it is known that the filter output, that is the predicted source signal ... -
Inversion for geometric and geoacoustic parameters in shallow water: experimental results
Gingras, Donald F.; Gerstoft, P. (NATO. SACLANTCEN, 1994/12)Experimental results on the estimation of both geometric and geoacoustic parameters in shallow water are presented. Genetic algorithms are used for estimation of the forward model parameters, the -
Parameter estimation using multi-frequency range-dependent acoustic data in shallow water
Gerstoft, Peter; Gingras, Donald F. (NATO. SACLANTCEN, 1996/11)The estimation of all forward model parameters - geometric, geoacoustic, -
Robust broadband matched-field processing: performance in shallow water by simulation
Gingras, Donald F. (NATO. SACLANTCEN, 1993/11)An issue of concern for matched-field processing is the strong dependence between performance and -
Single mode excitation, attenuation and backscatter in shallow water
Gingras, Donald F. (NATO. SACLANTCEN, 1995/10)Normal mode theory is used to illustrate that a vertical array of weighted sources driven in an
