摘要：A system for detecting ice on exterior surfaces of aircraft by transmitting arelatively low power microwave electromagnetic signal into a dielectric layer functioningas a surface waveguide, and monitoring the signals transmitted into and reflected fromthe waveguide. The waveguide includes a termination element which is mismatched withthe waveguide impedance, resulting in partial or total reflection of the microwave energyfrom the remote end of the waveguide. As ice builds up on the surface waveguide, theimpedance or reflection characteristics of the composite waveguide comprising the icelayer and the permanent surface waveguide give a reliable indication of the presence andlocation of the ice. The reflection characteristics are conventionally monitored utilizing adual directional coupler and a reflectometer.
