    This research examines methods for detecting unknown transient waveforms that are contaminated by noise. The sensitivity of the performance levels of the energy detector and the lack of knowledge about the structure of the transient waveform motivate the examination of other moment- or spectra-based detection techniques. We examine the performance of a bispectral energy detector and show that its ... View full abstract»

    This paper describes the simulation of backscattering of high frequency sound from complex objects and sand sea-bottom. Backscattering data from complex objects and seabottom were generated using a Universal High Resolution Imaging Sonar Simulation Toolkit (UHRISST) developed by the authors. Our approach here involves the approximation of objects and the sea-bottom through a series of facets that ... View full abstract»

  • Passive Doppler-bearing tracking using a pseudo-linear estimator

    Publication Year: 1995, Page(s):114 - 118

    In this paper an explicit pseudo-linear estimator for Doppler-bearing tracking is proposed. It overcomes the problems with the bias of earlier pseudo-linear estimators and with the nonlinear frequency measurement equation by using another representation than the Cartesian one and by using the logarithm of the frequency, respectively. It is fast, inherently stable, and easy to implement. The Dopple... View full abstract»

    Measurements and calculations in underwater and bio-acoustics should use for the units of the primary reference quantities the International System of Units commonly referred to as SI metric. Relative levels are important quantities provided the reference is clearly specified and the modifier to the term level is consistent with the units of the reference quantity. In particular it is necessary to... View full abstract»

    Ocean surface currents can be estimated, over a large coastal area, by utilizing the backscatter of high frequency (HF) radar waves from ocean gravity waves. Although the overall backscatter mechanism is complicated, the surface current information is contained within the spectral characteristics of two dominant Bragg components. The accuracy of the current estimate, following the usual FFT-based ... View full abstract»

    The broad scope of this study is to investigate whether the flow induced stimulation of naturally occurring luminescent plankton can be effectively utilized as a method of flow visualization in the field. The primary goal is to determine the nature of flow around a moving dolphin based on the luminescent response of in situ plankton to hydrodynamic stimulation View full abstract»
