Upper layer environmental parameters from CTD data - GIN '86 cruise
(NATO. SACLANTCEN, 1989/12)
The data from the SACLANTCEN June 1986 Cruise is analysed
Impact of uncertain environmental knowledge on the shallow-water transfer function
(NATO. SACLANTCEN, 1992/12)
It is assumed that the acoustic channel can be modeled as a linear time-invariant space-variant filter. In this case, from linear systems theory, it is known that the filter output, that is the predicted source signal ...
The application of coupled-mode theory to propagation in shallow water with randomly varying sound speed
(NATO. SACLANTCEN, 1987/06)
Sound propagation in the Baltic Sea cannot be described correctly by range independent propagation
A note on convergent zones
(NATO. SACLANTCEN, 1962/02)
An exact solution for ray paths near a sound channel with parabolic velocity profile is given for rays crossing the sound channel axis at small angles. The convergent zone for such rays for a source on axis is compared ...
Time series variability in fluctuating ocean waveguides
(NATO. SACLANTCEN, 1999/07)
The variability of signals propagating through an uncertain sound speed structure is addressed. Signals are assumed to travel in a narrow band adiabatically in modes and to experience fluctuations in sound speed which are ...
Passive ranging with the SNAP model: a performance study
(NATO. SACLANTCEN, 1987/07)
A passive ranging technique which uses SNAP, the SACLANT Centre's normal-mode model, is studied. An examination is made of the sensitivity of the technique to errors in the assumed sound
Celtic Duet - a joint SACLANTCEN/NRL shallow-water sea trial in Celtic Sea during July 1992: data summary
(NATO. SACLANTCEN, 1996/10)
In July 1992 a joint shallow-water sea trial was conducted in the
Principles and methods of core analysis at the SACLANT ASW Research Centre
(NATO. SACLANTCEN, 1967/08)
The methods and accuracy of measuring core parameters at the SACLANTCEN are described. Those for measuring sound velocity and electrical resistivity are explained in detail.
