Underwater ambient noise: proceedings of a conference held at SACLANTCEN on 11-14 May 1982, vol. 2 - Unclassified Papers, part 2
Contents: PROCESSING TECHNIQUES--A method of estimating the influence of ship's noise on ambient noise measurements; Optimal detection and tracking of acoustical noise sources in a time-varying environment; Influence of background- noise spatial coherence on high-resolution passive method; Performance of three averaging methods for various distributions; Is power averaging the best estimator for undersea acoustic data. MODELLING: DEVELOPMENT AND USE--A parametric examination of some properties of the low-frequency ambient-noise field; Detection models and target-information processing; The prediction of temporal statistics of directional ambient shipping noise; Site and frequency dependence of ambient noise in the north eastern Pacific Ocean; ACOUSTIC PROPAGATION EFFECTS--Site dependence of wind-dominated ambient noise in shallow water; Effects of topographic blockage and ocean boundaries on low-frequency noise fields; The seamount as a noise barrier.Contributors: Bendig, Horst Van ;Asselt, Hendrik ; Bienvenu, Georges; Nuttall, Albert H. ;Wagstaff, Ronald A. ; Fraser, I.
