    • The invention relates to a device for measuring the thickness of deposits on a surface, especially deposits of water or ice. The inventive device is characterized by a device for transmitting radar signals through the layer to be measured, a device for receiving the radar signals reflected by the interface of deposits facing away from the surface, and a device for determining the thickness of the deposits on the basis of a phase comparison of the radar signals emitted by the transmitter device and the radar signals received by the receiver device. The invention further relates to a device for measuring the thickness of the deposits on a surface, especially deposits of water or ice, by way of a dielectric resonator that is open in the direction of the deposits to be measured, an evaluation unit coupled to the dielectric resonator and supplying the dielectric resonator with a variable frequency, a detection unit for detecting the amplitude of the dielectric resonator depending on the supplied frequency, and a device for detecting the thickness of the deposits on the basis of the detected amplitude of the dielectric resonator and the supplied frequency. The invention further relates to a control unit for a defrost device having a corresponding device and a device that emits a signal to the defrost device for initiating its operation, if the device has detected that the deposits are ice. The invention further relates to the use of one of the above-mentioned devices for determining the depth of precipitation of water, ice and/or snow on a road surface, or for measuring the thickness of ice layers on the blades of wind turbines, or for measuring the thickness of ice layers on the airfoils of aircraft.
