(eng): This paper develops new quasi-Bayesian statistical models for the geometric deformation of a nominally linear towed array, based on rigorous fluid mechanics. The model accounts for the towing vessel's temporally correlated motion and the oceanic currents' space-time correlated behavior. The result is a correlation matrix of the sensor array transversal displacement, which can be used for Bayessian auto-calibration DOA estimation techniques, or to evaluate the best achievable DOA estimation accuracy.
