Abstract

Today, a large number of targets operate in space, and there are mainly four kinds of attitude targets: triaxial stabilized targets, spin stabilized targets, triaxial stabilized targets on tumbling, and spin stabilized targets on tumbling. It is of great significance to classify and identify these targets. First, the infrared radiation characteristic model of the target is established, taking different attitude targets into account, which, to the best of our knowledge, has seldom been considered. Then, through the simulation of specific example targets, the differences in infrared characteristics of four kinds of attitude targets are analyzed and explained. Finally, according to the orbit distribution and typical geometry structure of space targets, the infrared characteristic data sets of four kinds of attitude targets are simulated, and a classifier is established to classify and recognize these targets. The results show that the infrared characteristics of different attitude targets are obviously different, and the classifier can successfully classify and recognize different attitude targets.
