Acoustic characterization of seafloor sediment employing a hybrid method of neural network architecture and fuzzy algorithm
(IEEE, 2009)Seafloor sediment is characterized acoustically in the western continental shelf of India using the echo features extracted from normal incidence single-beam echo sounder backscatter returns at 33 and 210 kHz. The seafloor ... -
Algorithms and interface for ocean acoustic ray-tracing (Developed in MATLAB)
(National Institute of Oceanography, 2005)An integrated friendly-user interactive ocean application package has been developed for computation of eigenrays for a given source - receiver configuration and subsurface and bottom environmental conditions utilizing the ... -
Numerical simulation and measurements of acoustic transmissions from Heard Island to the equatorial Indian Ocean
(NISCAIR, CSIR, 1996)Simulated acoustic propagation showed a gradual deepening of the ray paths from the southern ocean towards tropics. Also the axis of the sound channel deepens from 150 m to 1600 m. Sudden jumps were noticed in the acoustic ... -
Studies on normal incidence backscattering in nodule areas using the multibeam-hydrosweep system
(Cochin Univ. Sci. and Technol., Cochin, India, 1995)The acoustic response from areas of varying nodule abundance and number densities in the Central Indian Ocean has been studied by using the echo peak amplitudes of the normal incidence beam in the Multibeam Hydrosweep ...
