A radar device for transmitting a signal in a frequency range with a control system and an oscillator. An input of the oscillator is connected to the control system via a converter. The oscillator can be activated by the control system to generate the signal and the signal generated by the oscillator can be tapped at an output of the oscillator, with at least one transmission antenna for transmitting the signal at the output of the oscillator. The transmission antenna is connected to the output of the oscillator, with at least one receive channel for receiving a receive signal, for processing the receive signal and for forwarding the processed receive signal to the control system. The receive channel features at least one receive antenna and a mixer for mixing the receive signal with the signal at the output of the oscillator. The mixer is connected to the output of the oscillator. A frequency divider is provided that feeds signals from the oscillator to a frequency counter. At a minimum, the oscillator and the frequency divider are designed as a monolithic microwave integrated circuit.
