Abstract
An infrared search device for the detection and engagement of enemy helicopters is so designed that an IR Sensor in the focal plane of the IR Optics of the search head includes a 2-demensional matrix of point-shaped detector cells. The detector cells operate in a wavelength range of between 3 and 14 um or a fraction thereof. To determine the offset angle of the helicopter from the optical axis of the device, the cells are interrogated individually and in succession by an analysis unit in such a manner that all measurement values are obtained almost simultaneously.
