Abstract

Possible techniques for suppressing or removing ice from large radar antennas located in the Arctic were investigated. Of immediate concern were the original Ballistic Missile Early Warning System antennas, which were too large to enclose in radomes. The icing rates of various parts of the antennas and of the antennas as a whole were determined. Ice suppression by nucleation and deflection was studied, and mechanical removal was evaluated.
