2. A method for operation of a radar sensor in the near area for production of a detectable coverage field (5) for the identification of people and/or stationary objects by means of an antenna, wherein a presence sensor (7) is equipped with an FMCW radar for distance measurement, and/or a radar sensor (R1 to R4) is equipped with at least one independent auxiliary antenna (10) for carrying out a self-test.
- 10. A method for operation of a radar sensor in the near area for production of a detectable coverage field (5) for the identification of people and/or stationary objects by means of an antenna, wherein stationary objects can be located and determined on the basis of their size and location by means of a presence sensor (7) using an FMCW radar for distance measurement in a coverage field (9), by determination of phase shifts and delay times of the reflected signals.
- 13. A radar sensor for production of a detectable coverage field (5, 9) for identification of people and/or static objects in the near area by means of an antenna (3), wherein the antenna (3) is in the form of a plurality of end-fire antennas, in particular slot antennas (3) or patch antennas.
- 27. A radar sensor for production of a detectable coverage field (5, 9) for identification of people and/or static objects in the near area by means of an antenna (3), wherein the antenna (3) is associated with at least one transmitter and one receiver, and the size, the position and/or the height of an object can be determined within the preselected coverage field (9) by determination of different delay times and/or phase shifts of the received signals, with the transmitter or transmitters and receiver or receivers being locally at a distance from one another.
