Abstract

A radar system is described. In accordance with one example implementation, the radar system comprises a passive coupler arrangement and also a first radar chip, a second radar chip and a third radar chip. The radar chips each comprise at least one external RF contact and also a local oscillator designed to generate an RF oscillator signal at least in a switched-on state. The external RF contacts of the radar chips are coupled via the coupler arrangement in such a way that, in a first operating mode, the RF oscillator signal can be transferred from the first radar chip via the coupler arrangement to the second radar chip and the third radar chip, and that, in a second operating mode, the RF oscillator signal can be transferred from the second radar chip via the coupler arrangement to the third radar chip.
