Abstract: In the confrontatoin environment with complex background and infrared decoy flares, aerial target recognition by infrared imaging of fortification storming/HEAT missiles remains a challenge. For the problem of aerial target recognition, an anti-interference recognition algorithm with strong discriminative features is proposed, which integrates region generation, feature learning, classification and identification into the anti-interference algorithm to form an abstract recognition framework from the pixel level to region level and then to feature recognition step by step. Firstly, by simulating the typical battlefield environment, a large number of target feature libraries under different confrontation situations are generated, which serve as the basis of the algorithm research. Secondly, region proposals are formed by pixel similarity clustering, and “coarse granularity” location of regions is completed. Then the extracted region features are input into the feature selection module to learn the strong discriminative features. Finally, the selected features are input into the improved multi-classification support vector machines (SVM) for target classification and recognition, and the “finer granularity” locking of the target region is realized. Through the recognition mechanism of gradual refinement, aerial targets in the complex battlefield confrontation environment are recognized. The validation experiments show that the algorithm has an average recognition accuracy rate of 78.63% in the ballistic image datasets under different confrontation situations, which can effectively distinguish between targets and interference, and provide support for the development of algorithms in engineering applications.
