Channel sensitive processor: real data processing
Haralabus, Georgios (NATO. SACLANTCEN, 1998/02)The CSP is applied to data collected during the DUSS97 sea trial. A one-way geometry is used and the transmitted signal propagation time is known a priori. As predicted by analytical and simulation studies, the CSP detector ... -
Channel sensitive processor: sensitivity and optimization study
Haralabus, Georgios (NATO. SACLANTCEN, 1997/10)The detection performance of the Channel-Sensitive Processor (CSP) has been tested in dense multipath conditions. It was demonstrated that, for a known propagation channel, the CSP outperforms the conventional matched ... -
Channel-sensitive processor: development and detection performance evaluation
Alexandrou, D.; Haralabus, Georgios (NATO. SACLANTCEN, 1997/03)A Channel Sensitive Processor (CSP) which improves upon the detection performance of the traditional matched filter is developed. This method compensates for the performance degradation of the matched filter due to dense ... -
DUSS97: source localization and environmental inversion using vertical array data
Waldhorst, A.; Haralabus, Georgios (NATO. SACLANTCEN, 1998/08)Results on source localization and environmental inversion using experimental data acquired on a vertical line array are presented. Global inversion methods based on genetic algorithms are utilized to estimated the range ... -
Source localization in shallow water using multi-frequency processing of shot data
Haralabus, Georgios; Gerstoft, P. (NATO. SACLANTCEN, 1996/07)Multi-frequency processing methods are applied to real data generated by explosives to examine the -
Statistical characteristics of large-scale bottom reverberation
Haralabus, Georgios (NATO. SACLANTCEN, 1995/07)Simulation results from a statistical characterization of large-scale bottom reverberation from broadband signals are presented. The seafloor profile is parametrized via the surface root-mean-square height and correlation ...
