Radar system comprising a plurality of radar chips

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 radarchip. 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 contactsof 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 (3). 本公开涉及一种雷达系统。根据一个实施例，雷达系统具有被动耦合器装置以及第一雷达芯片、第二雷达芯片和第三雷达芯片。每个雷达芯片具有至少一个外部HF触点以及本地振荡器，本地振荡器被构造成至少在导通状态下产生HF振荡器信号。雷达芯片的外部HF触点通过耦合器装置耦合，使得在第一运行模式中，HF振荡器信号可以从第一雷达芯片通过耦合器装置传输到第二和第三雷达芯片，并且在第二运行模式中，HF振荡器信号可以从第二雷达芯片通
