An apparatus 1 for detecting approaching objects comprises a rotating radar device 2, an infrared camera 3 and a signal processing and evaluation unit 4. The infrared camera is mounted directly on the radar device and has at least one infrared detector 3.1. The signal processing and computing unit receives detection signals captured by the radar device and the infrared camera and is configured to use the received detection signals to determine whether an approaching object is present. The infrared detector, which may be an area detector, can be arranged such that its rows or columns run parallel to a direction of the rotation of the radar device. The signal processing and evaluation unit may correlate the received signals, carry out a convolution operation on pixels contained in the detection signals from the infrared camera, or detect an approaching object through use of a threshold value analysis. An approaching object may only be detected by the apparatus if the object is detected in the signals from the radar device and the signal from the infrared camera. |
