Claim 18:
19. A method of determining a thickness of ice accumulated on a surface of a RADAR system using a sensor unit coupled to the RADAR system, comprising:
tuning a sensor unit antenna to a harmonic of a signal transmitted by the RADAR system, the harmonic falling within an ice absorption band;
emitting the harmonic, from the sensor unit antenna, through the ice, at a first signal strength;
receiving the harmonic at the sensor unit antenna;
detecting, using a sensor unit receiver communicatively coupled to the sensor unit antenna, a second signal strength of the harmonic received by the sensor unit antenna;
determining, using the sensor unit receiver, an attenuation of the harmonic based on the first signal strength and the second signal strength; and
determining a thickness of the ice based on the attenuation of the harmonic and an attenuation rate of the ice absorption band.
