Model of description of the process of functioning of combined correlation-on-extremal system of navigation of the unbeiled flying apparat

Abstract

The results of the development of a formalized model of the process of functioning of a combined correlation-extreme navigation system are presented. The factors that lead to the formation of a multi-extremal decision function of a combined correlation-extreme navigation system are determined. The model of the current image, which is formed by separate channels according to informative features, is made more precise, depending on the spatial position of the pilotless flying device. A block diagram of the description of the process of functionalization of a combined correlation-extreme navigation system is presented. The influence of the three-dimensional shape of the sighting surface objects on the effective antenna temperature of the radiometric channel was taken into account, which allowed the refinement of the radiometric current image description model depending on the informative signs of the images. The model of the formation process of the solving function of the combined correlation-extreme navigation system is clarified, taking into account the influence of the three-dimensional shape of the sighting objects and random changes in the spatial position of the flying apparatus. Relations are obtained for describing the current images of the sighting surface in the radiometric and television channels of a combined correlation-extreme navigation system, taking into account the three-dimensional shape of the objects of interference and random changes in the spatial position of the aircraft caused by the turbulence of the atmosphere. An expression describing the process of formation of the solving function of a combined correlation-extreme navigation system is presented. Variants of the scenario for the formation of a decisive function are presented depending on the conditions of the operational-tactical situation. The expediency of forming a single standard for television and radiometric channels of a combined correlation-extreme navigation system is substantiated.
