Abstract

After a decoy is released, it can fly around the target aircraft in a short period of time. And it can radiate infrared spectral radiation similarly to the target do. So it is difficult to recognize the target aircraft. But in infrared images, decoys and targets have different geometrical features. So an infrared decoys recognition method based on the geometrical features is proposed in this paper. The geometrical features of the candidates in each image are extracted, such as the major axis, the minor axis, the aspect ratio, area etc. Then the differences on these geometrical features can be used to recognize targets and decoys. A simulation was done on a set of images that contain decoys and targets by using this method. The results show that the algorithm proposed in this paper can better distinguish infrared decoys and targets.
