Abstract
A radar device for transmitting and receiving a signal in a frequency band for target detection. The invention includes a control means, an oscillator, with an input of the oscillator being connected via a converter to the control means, with it being able to address the oscillator via control means in order to generate a signal, and with it being possible to tap the signal generated via the oscillator at an output of the oscillator, at least one transmission antenna for transmitting the signals provided at the output of the oscillator, with the transmission antenna being connected to the output of the oscillator, and at least one receiver channel for receiving a receiver signal, for processing the receiver signal, and for forwarding the processed receiver signal to the control means, with the receiver channel comprising at least one receiving antenna for receiving the receiver signal and a mixer for mixing the receiver signal with the signal provided at the output of the oscillator, and with the mixer being connected to the output of the oscillator.
