A radar system includes a first integrated radar circuit having a plurality of first transmission paths and a local oscillator configured to generate a local oscillator signal. The first integrated radar circuit has a first terminal configured to output an oscillation signal based on the local oscillator signal. The radar system includes a second integrated radar circuit having a second transmission path and a second terminal. The radar system includes a partially reflective element coupled to the first terminal via a first line section and to the second terminal via a second line section. The partially reflective element is configured to reflect back a first portion of the oscillation signal as a reflected signal via the first line section to the first terminal and to pass on a second portion of the oscillation signal as a forward signal via the second line section to the second terminal.

Radar system, integrated radar circuit and method for a radar system

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.
