Non-Rayleigh Acoustic Scattering Characteristics of Individual Fish and Zooplankton [PDF]
IEEE Journal of Oceanic Engineering, 2004 It has long been known that the statistical properties of acoustic echoes from individual fish can have non-Rayleigh characteristics. The statistical properties of echoes from zooplankton are generally less understood. In this study, echoes from individual fish and zooplankton from a series of laboratory measurements from the past decade are ...
