Abstract
A method, apparatus, and system to remotely acquire information from volumes in a snowpack and to analyze the information are disclosed. Electromagnetic energy is transmitted remotely to a region of interest in a snowpack and data about reflections are processed to determine reflection values for different volumes within the snowpack. The frequency of the transmit signal is modulated and the positions from which energy is transmitted and received are changed to create a two-dimensional synthetic aperture that allows reflections from three-dimensional volumes to be discriminated and resolved. The electromagnetic energy is transmitted to ensure that it arrives at the snowpack at shallow grazing angles to maximize returns from volumes in the snow and to minimize boundary reflections from the ground.
