Review of numerical models in underwater acoustics including recently developed fast-field program
(NATO. SACLANTCEN, 1984/12)
Two papers given by SACLANTCEN personnel at the NATO Advanced Research Workshop on Hybrid Formulation of Wave Propagation and Scattering at Castel Gandolfo, Rome, Italy on 30 August to 3 September 1983 are published as a ...
Scintillation instrument for remote environmental analysis (SIREN)
(NATO. SACLANTCEN, 1999/02)
A high frequency acoustic propagation instrument which was developed to study ocean variability in the Strait of Istanbul (Bosporus) is described. The scintillation instrument for remote environmental analysis (SIREN) was ...
A note on attenuation and dispersion in marine sediments
(NATO. SACLANTCEN, 1989/04)
From the more recent investigations reported ill the literature,
Theoretical calculation of transmission loss in the ocean
(NATO. SACLANTCEN, 1971/12)
The topic that is dealt with in this paper is a method for c omputation of acoustic transmission loss by sound propagation in the ocean. The method i s based on the ray theory which is used in connection with an acoustic ...
Methods used in France for the calculation of sound fields
(NATO. SACLANTCEN, 1971/12)
Status of ray theory development of Naval Undersea Research and Development Center
(NATO. SACLANTCEN, 1971/12)
The first part of this paper discusses NUC (Naval Undersea Research and Development Center) work on the accuracy and validity of ray theory. By comparing the range to convergence zones as indicated by experiment and by ...
An acoustic, high resolution, sediment profiler
(NATO. SACLANTCEN, 1966/11)
An acoustic sediment profiler is described that utilizes short 50 kHz pulses to achieve a high range resolution. In trials in shallow water, penetration depths of about 9 m and resolution of about 25 cm were obtained. ...
