DEVELOPMENT OF METHODS FOR MATHEMATICAL MODELING OF THE THERMAL CORRELATION-EXTREME NAVIGATION SYSTEM OF THE AIRCRAFT

Abstract

Reviewed simulation model of correlation-extreme navigation system (CASN) of the aircraft (A/C) using the microwave radiation of the earth's surface, allowing to optimize system performance, ranging from the kind of used signal and the diagram of the radiometer to the expected positional accuracy of CASN. The developed model consists of the simulation of the radiometer; block modelling the radiating properties of the underlying surface, the unit of account of the influence of the atmosphere; block kinematics modeling of the movement of the carrier, the characteristics of the antenna system and method of the review space; the unit for computing the coordinates. These model allows to estimate the information content and the stability of the radiation of the earth surface plot of the correction of the trajectory, the influence of
