Abstract

A radar system having at least one radar transmission unit, at least one radar reception unit, a central unit, and a glass fiber for connecting these units, wherein the central unit has a central optical transmission unit to provide an optical radar driver signal, and wherein the at least one radar transmission unit has an optical reception unit and a radar transmitter, wherein the optical reception unit receives the optical radar driver signal and converts the optical radar driver signal into an electrical radar driver signal and provides the electrical radar driver signal for driving the radar transmitter, wherein the at least one radar reception unit includes a radar receiver, a mixer and an optical modulation unit. Also disclosed is an associated method.
