Acoustic characterization of a shallow water site
Cable, P.; Marshall, W.; Kooij, Theo; Skarda, G.; Waldman, K. (NATO. SACLANTCEN, 1993/08)Results are presented from an exercise aimed at providing a low frequency active sonar environmental characterization of a specific shallow water site in the Gulf of Mexico. Downward refracting acoustic transmission and ... -
Spatial and temporal coherence in a long range, upslope environment
DeDominicis, Theresa S.; Kooij, Theo (NATO. SACLANTCEN, 1993/08)In an active acoustic test conducted off the USA Pacific Coast in November-December 1991, a low-frequency source, kept stationary over the deep basin, insonified from long range the coastal slope and shelf. An autonomous, ... -
The influence of quantizing and sampling on the signal-to-noise ratio of a complex correlator
Kooij, Theo; Laval, Robert (NATO. SACLANTCEN, 1967/09)The combined effects of sampling and phase-quantizing of phase- modulated signals in Gaussian noise are studied and expressed in terms of the output signal-to-noise ratio of a matched filter correlator. The obtained results ...
