Radar sensor system and method for operating a radar sensor system

A radar sensor system, comprising:

• a defined number of HF components, each of the HF components having at least one antenna for transmitting and/or receiving radar waves, and at least one antenna control for operating the at least one antenna;
• and
• a synchronization network to which all of the HF components are functionally connected and via which an HF signal is able to be supplied to all of the HF components;
• wherein at least two of the HF components have a self-supply device configured to feed back a defined share of power of the HF signal able to be fed into the synchronization network, the HF signal for all of the HF components being able to be generated by a defined one of the HF components at a defined instant;
• and
• wherein the radar sensor system is able to be functionally subdivided into at least two sub-sensor systems.
