A system for target recognition and tracking based on radar and infrared image sensors is presented, which can make use of the complement and redundancy of data from different sensors to improve the precision of target recognition and tracking and the robustness and reliability. For data fusion at characteristic level, characteristics of a target obtained from radar can be used in the IR image-based subsystem to improve the ability of object recognition, and vice versa. The process of target recognition based on IR image analysis is composed of image enhancement, image segmentation and recognition of segmented images. The recognition of segmented objects is divided into two classes: recognition of dot targets and area targets.
