Infrared decoys recognition method based on dual-band information fusion

Targets recognition is an important and difficult task in infrared guidance technology. But with the development of different kinds of infrared decoys, it is difficult to recognize targets from decoys only by information from single-band detectors. In order to improve targets recognition ability from decoys, more information should be used. In this paper, infrared radiation features of targets, infrared decoys and background are analyzed. Research shows that targets and decoys have differences in the thermal energy distribution in different bands because of their difference in material composition. Based on this difference, this paper proposes an information fusion method that fuses information from dual-band detectors to detect and recognize targets. Experimental results show that this method has a better performance compared to the method which only use information from single-band.
