Approximate far‐field, backscattering transient responses are shown for three ice‐sphere sizes. Signal ringing continues for a longer time, but the effective transient decay time is less than a space‐equivalent time of six diameters. Glory, axial, and stationary rays in combination with an internal surface wave of one cut are the principal contributors to the scattering by ice, but the dipole must be included for small electrical sizes.
