Matched field and matched beam source localization using a bottom moored horizontal arrayBarlee, R. Matthew S. (Richard Matthew Scott) 10 April 2008 (has links)
Presented is an analysis of the performance of a matched field and matched beam processor in localization of a shallow water source using a 63-element bottom-moored planar array. Two scenarios are considered: in the first, a stationary, submerged CW source is localized in a high SNR environment; in the second, the source is being towed in the presence of multiple ship-generated directional noise sources. Array element localization is carried out using regularized linear inversion on transients from light bulb implosions around the array. The method provides the simplest array shape solution while still fitting the data and initial hydrophone position estimates to a statistically appropriate level. Estimation of geoacoustic parameters is accomplished using a hybrid inversion algorithm producing a robust geoacoustic model which is subsequently used to produce replica acoustic fields for the full field localization methods. Localization proved highly successful for the first scenario, while increased noise and geometrical limitations led to moderate performance in the second scenario.
