Parallel recognition for military target in dual band using a joint transform correlator

Facing the large amount of optical reconnaissance images, how to improve the reconnaissance efficiency and accuracy has become an urgent problem to be solved. In our designed scheme, the joint transform correlator is utilized to achieve the aim of recognizing military target in dual band. By monitoring the distribution of correlation points from correlation output results, our designed scheme can judge whether there are targets in visible band and infrared band reconnaissance images. This recognition method can not only improve the recognition ability for camouflaged targets, but also greatly improve the target recognition speed with the help of the recognition speed advantage of the joint transform correlator. Theoretical analysis and simulation experiments both verify the feasibility of this method.
