Radar system having a centrally configured analysis unit

1. A radar system for a vehicle, comprising:

at least one central control unit for sending data and for processing received data;

at least one radar sensor head that is situated at a distance from the at least one central control unit and that has at least one transmit antenna for producing radar waves and at least one receive antenna for receiving radar waves; and

at least one data line between the at least one central control unit and the at least one radar sensor head;

wherein the at least one radar sensor head has an analog-digital converter for converting the radar waves received by the at least one receive antenna into digital measurement data, the at least one central control unit having an analysis unit, connected downstream from the at least one data line, for carrying out a processing step over at least a part of the digital measurement data.

2. The radar system as recited in claim 1 , wherein the at least one analysis unit is configured to carry out a Fourier transformation and/or an orthogonal frequency-division multiplexing method, and/or at least one correlation, being capable of being carried out by the at least one analysis unit connected downstream from the at least one data line.

3. The radar system as recited in claim 1 , wherein the digital measurement data is marked with at least one item of time information in the at least one radar sensor head.

4. The radar system as recited in claim 1 , wherein the digital measurement data produced by the analog-digital converter is transmitted in packets to the at least one central control unit through the at least one data line.

5. The radar system as recited in claim 3 , wherein the digital measurement data is transmitted to the at least one central control unit through the at least one data line, and is synchronized with the at least one radar sensor head in the at least one central control unit through the at least one item of time information.

6. The radar system as recited in claim 3 , wherein the at least one item of time information is produced by a time and control device situated in the at least one radar sensor head.

7. The radar system as recited in claim 6 , wherein the at least one radar sensor head has a frequency synthesizer for producing a carrier frequency of the at least one transmit antenna, and the frequency synthesizer is adjusted by the at least one central control unit through the time and control device.

8. The radar system as recited in claim 1 , wherein respective frequency synthesizers of at least two radar sensor heads of the at least one radar sensor head are synchronized with one another through the at least one central control unit.

9. The radar system as recited in claim 1 , wherein the data transmitted through the at least one data line is transmitted with a higher data rate than a reference frequency of the at least one transmit antenna of the at least one radar sensor head.

10. The radar system as recited in claim 1 , wherein the at least one central control unit has at least one processor for carrying out computing operations, the analysis unit for transforming digital measurement data, at least one memory for at least temporary storage of digital data, and a time and control device for synchronizing the digital measurement data.
