Measuring ship acoustic signatures against mine threat
conference paper
The NATO standard ‘AMP-15’ [1] provides procedures for the measurement and reporting of the acoustic signature of ships and for the establishment of acoustic signature goals to counter the naval mine threat. Measurements are carried out at dedicated shallow water acoustic ranges. Measurements according to this procedure of the same ship at the same operational condition but at different acoustic ranges may lead to different results. These differences are caused by differences in geometry and properties of water and seabed, in combination with the processing of the acoustic data according to the AMP-15 procedure. These effects are investigated by means of theoretical, numerical and experimental evaluations of the procedure, applied to a compact controlled sound source, leading to a better understanding of the assumptions and uncertainties associated with the reported ship signatures.
