Generic Oceanographic Array Technologies (GOATS)'98: bi-static seabed scattering measurements using autonomous underwater vehicles
Schmidt, Henrik; Maguer, Alain; Bovio, Edoardo; Fox, Warren L. J.; LePage, Kevin D.; Pace, Nicholas G.; Hollett, Reginald D.; Guerrini, Piero; Sletner, Per Arne; Michelozzi, Enzo; Moran, B.; Grieve, R. (NATO. SACLANTCEN, 1998/10)The GOATS'98 experiment was performed May 5-29, 1998 in shallow water off Marciana Marina, on the island of Elba, Italy. The experiment addressed some of the fundamental issues associated with using the new Autonomous Ocean ... -
High frequency acoustics in shallow water: proceedings of a conference held in Lerici, Italy, 30 June to 4 July, 1997, organized and sponsored by the NATO SACLANT Undersea Research Centre
High frequency acoustics in shallow water (1997 June 30 - July 4 : Lerici, Italy) (NATO. SACLANTCEN, 1997) -
Penetration of acoustic waves into sandy seafloors at low grazing angles: the Helmholtz-Kirchhoff approach
Pouliquen, Eric; Lyons, Anthony P.; Pace, Nicholas G. (NATO. SACLANTCEN, 1998/08)The Helmholtz-Kirchhoff integral is applied to model the penetration of sound waves into sandy seafloors at grazing angles above and below the critical angle. Although the conditions for the validity -
Time-evolution modelling of seafloor scatter: Part 1: Theory
Pouliquen, Eric; Bergem, Oddbjorn; Pace, Nicholas G. (NATO. SACLANTCEN, 1997/04)A time-series model for acoustic seafloor backscattering is described. -
Time-evolution modelling of seafloor scatter: Part 2: experimental verification
Bergem, Oddbjorn; Pouliquen, Eric; Canepa, Gaetano; Pace, Nicholas G. (NATO. SACLANTCEN, 1997/04)A time-evolution model of seafloor scatter is numerically implemented and experimentally verified. The model is based on expressing analytically the elementary time-backscattered response of every seafloor surface and every ...
