Patent ID: 8847814

Claim:
An FMCW radar sensor for a motor vehicle, comprising: a high frequency part for generating, transmitting and receiving radar signals; a modulation device for controlling the modulation of the transmitted radar signal; at least one analog preprocessing stage for an intermediate frequency signal formed from the received radar signal; at least one analog/digital transducer stage; and a processor for controlling the modulation device and for further processing the digital signals of the analog/digital transducer stage; and a clock pulse signal generator; wherein: the modulation device, the preprocessing stage, the analog/digital transducer stage, and the clock pulse signal generator are integrated into a single semiconductor component that (a) is separate from the high frequency part, and (b) includes a monitoring device and registers for the configuration and monitoring of the components of the semiconductor component, and an interface to the processor; and the clock pulse signal generator supplies a uniform clock pulse signal to the modulation device, the preprocessing stage, and the analog/digital transducer stage which are configured to use the received clock pulse signal to coordinate their respective functions.
