Transient Localization in Shallow Water Environments

摘要: Abstract : In this work, the robustness of a simple, Bartlett-type processor based on matching broadband signal autocorrelation functions is investigated. Measures to be examined include size localization footprint ambiguity surface and peak-to-sidelobe levels in presence environmental mismatch noise. A full-wave PE model used produce replicas. Both model-generated synthetic signals, which provide baseline results, measured pulses shallow water environment are analyzed. This work suggests that has more significant effect performance than It also that, as long noise level not higher level, will significantly affected. expected, since for white majority influence function occurs at zero lag been removed algorithms. shown time-domain generally useful smaller bandwidths low frequencies, observed previous whereas frequency-domain better suited larger frequencies.
