Abstract
A radar transmitter is described. The radar transmitter may include the following: a transmit channel which is designed to receive a local oscillator signal and to generate a high-frequency (HF) radar signal based on the local oscillator signal; a phase shifter contained in the transmit channel which is designed to set a phase of the HF radar signal depending on an input phase value; and a coupler contained in the transmit channel which is designed to receive the HF radar signal and output the HF radar signal at an output contact. A phase controller circuit is assigned to the transmit channel, where the circuit is coupled with the coupler and is designed to receive the local oscillator signal and the HF radar signal, and to adjust the input phase value for the phase shifter based on a phase difference between the local oscillator signal and the HF radar signal.
