On the Identification of a Stochastic Response Model in Active Sonar

Abstract

The detection of a marine target with the aid of an active sonar necessitates a probabilistic model of the phenomena, and detection improves according to how well the model takes account of the various random and deterministic physical phenomena. The signal wave Z(t) received from a point source x of the target is described by a deterministic scalar or vector function G(t,x). Random reflection is characterized by a scalar multiplying factor C(x), randomly distributed according to a mixture of central Gaussian laws.
