4. Effects of orientation on acoustic scattering from Antarctic krill at 120 kHz

   . superb a DWBA scattering model is proposed that is scalable by animal length. With good orientation ... approximation (DWBA) method were developed for five animals and compared with the measurements. Both measured ... and modeled scattering patterns showed that 120 kHz acoustic scattering levels are highly dependent on ... animal orientation. Use of these scattering patterns with orientation data from shipboard studies of E ...
