Acoustic Scattering Kernels from Arctic Sea Ice.

A new algorithm for computing scattering kernels from Artic ice keels is described. The basic equations are adapted from Burke and Twersky (1966) but the algorithm does not involve approximations in the limits of low or high frequencies, and is therefore more accurate. Calculations over a range of f...
