ABSTRACT:
The invention is a system for determining the presence of ice on the surface of a structure. The system includes a guard layer mounted to the surface. A non-conductive layer is mounted on top of the ground plane. First and second electrodes made of a resistive material mounted on the non-conductive layer. First and second electrical leads having first ends of attached to first and second electrodes, respectively. The first and second leads having impedance equal to the impedance of the first ends thereof with the impedance of the first and second leads decreasing toward the second ends thereof.
