Performance of acoustic spread-spectrum signaling in simulated ocean channels
(Monterey, California. Naval Postgraduate School, 2003-06)
Direct-Sequence Spread Spectrum (DSSS) modulation is being advanced as the physical-layer basis for Seaweb undersea acoustic networking. DSSS meets the need for channel tolerance, transmission security, and multi-user ...
Amplitude shading and phase weighting of a vertical linear array in the SOFAR channel by the linear minimum variance estimation technique
(Monterey, California. Naval Postgraduate School, 1983-12)
A single linear vertical passive array is used in the 'SOFAR' channel to determine the depth of a single underwater source at a constant range. The phase and amplitude weights applied to the array are determined by the ...
