Abstract

A study of sea and ice sheet surface impulse responses measured at 150 MHz is reported. The presence of both coherent and noncoherent returns is observed due to the low frequency of observation, and attempts to interpret the observed wave-forms are presented. Further analysis using a Monte Carlo simulation of one dimensional surface impulse responses suggests that the physical optics theory should be applicable for modeling the observed waveforms so that they can be used in sensing ice sheet surface properties.
