Abstract

A radar sensor head for a radar system, including: at least one transmitting antenna for generating, and at least one receiving antenna for receiving, radar waves; an interface for connecting the radar sensor head to a data lead; and an identification unit for identifying the radar sensor head, a downloading of calibration data of the sensor head to a central control apparatus being initiatable by way of the identification unit.

First claim

What is claimed is:

1 . A radar sensor head for a radar system, comprising:
at least one transmitting antenna for generating radar waves, and at least one receiving antenna for receiving radar waves; an interface configured to connect the radar sensor head to a data lead; and an identification unit configured to identify the radar sensor head, the identification unit configured to initiate a downloading of calibration data of the radar sensor head to a central control apparatus.

2 . The radar sensor head as recited in claim 1 , further comprising:
a preprocessing unit configured for defined preprocessing of received data.

3 . The radar sensor head as recited in claim 1 , wherein the calibration data are updatable using the identification unit.

4 . The radar sensor head as recited in claim 1 , wherein the downloading of the calibration data is executable in wireless or wire-based fashion.

5 . The radar sensor head as recited in claim 1 , wherein in conjunction with the downloading of the calibration data, an enabling of the radar sensor head is executable.

6 . The radar sensor head as recited in claim 1 , wherein a sensor ID is transferrable using the identification unit.

7 . The radar sensor head as recited in claim 6 , wherein the sensor ID is transferrable in encrypted or signed fashion using the identification unit.

8 . The radar sensor head as recited in claim 6 , wherein a public key of an encryption method is transferrable as the sensor ID.

9 . The radar sensor head as recited in claim 1 , wherein the calibration data are at least one of the following: (i) typical noise level, (ii) antenna properties, (iii) amplitude/phase deviations, (iv) position of antenna elements, (v) temperature properties, (vi) temperature profile.

10 . The radar sensor head as recited in claim 1 , wherein the radar waves received by the at least one receiving antenna are converted by an analog/digital converter into digital measured data, and are labeled with at least one time datum.

11 . A radar system, comprising:
at least one radar sensor head including at least one transmitting antenna for generating radar waves, and at least one receiving antenna for receiving radar waves, an interface configured to connect the radar sensor head to a data lead, and an identification unit configured to identify the radar sensor head, the identification unit configured to initiate a downloading of calibration data of the radar sensor head to a central control apparatus; the central control apparatus being configured to transmitting data and process received data, the central control apparatus having a linking unit to a server for downloading calibration data; and the data lead being between the central control apparatus and the at least one radar sensor head.

12 . The radar system as recited in claim 11 , wherein the central control apparatus has at least one calibration data memory.

13 . A method for manufacturing a radar sensor head, comprising the following steps:
furnishing at least one transmitting antenna for generating radar waves, and at least one receiving antenna for receiving, radar waves; furnishing an interface configured to connect the radar sensor head to a data lead; and furnishing an identification device configured to identify the radar sensor head, a downloading of calibration data of the radar sensor head to a central control apparatus being initiable using the identification device.
