Reconciling theoretical versus empirical target strengths of krill; effects of phase variability on the distorted wave Born approximation
Abstract: A model was recently proposed to predict the target strengths (TS) of Antarctic krill ... of a discretized bent cylinder (krill model) causes a dramatic flattening in the side-lobe regions of TS(?), while ... negligibly affecting the main scattering lobe. These results are consistent with the krill TS measurements ... accurate and thus practical tool is developed for predicting krill TS. Author(s): D.A. Demer and S.G ...
