Abstract
A method for distance measurement and data transmission in a continuous wave radar system is described. A continuous wave radar system has a transmit and receive module and at least one transponder device, a mobile control and monitoring device and an HMI system. Transponder devices are searched for with the aid of an unmodulated continuous wave signal as an interrogation signal, such that the transponder device can send a radio response signal to the transmit and receive module in response to the interrogation signal, as a result of which a data transmission takes place from the transponder device to the transmit and receive module. Upon completion of the data transmission a frequency-modulated continuous wave signal is generated in order to measure, on the basis thereof, a distance between the transponder device and the transmit and receive module.
