Self-guiding of a high velocity pilotless aircraft on the terminal flight leg in atmosphere

An algorithm for self-guiding of a high velocity aircraft with high aerodynamic quality on the terminal flight leg in the atmosphere is proposed. This algorithm provides guiding to a given spatial domain with required high accuracy and the conditions of approaching this domain in the case of uncertain aerodynamic characteristics of the aircraft and the action of a wide spectrum of uncontrollable factors of different physical nature. The algorithm consists in the formation of an updated incident trajectory using the data of a multispectral observation system. The results of simulation of the process of terminal guiding of a high velocity aircraft using the proposed algorithm in different conditions are presented; these results prove the possibility of achieving high terminal accuracy and weak sensitivity of the algorithm to the action of uncontrollable factors.
