Continuous wave radarsystem for distance measurements and data transmission

摘要

The system has a transmitting and receiving module, a mixer (134) and a transponder device (108) that transmits radio response signals in response to request signals, where the response signals can be modulated with phase and amplitude modulations. The phase modulation serves for distance determination between the modules and the device, while the amplitude modulation allows a data transmission from the device to the modules. The phase modulation is a phase shift keying modulation, and the amplitude modulation is an on/off keying modulation. The two modulations have two different modulating frequencies. An independent claim is also included for a HMI system with a mobile operating and monitoring device for the automation components of a technical system and with a continuous wave radar system for localization of the mobile operating and monitoring device.
