Практичні аспекти оптимальної обробки сигналів в інформаційно – вимірювальних системах за умов апріорної невизначеності

Abstract

In the conditions of rapid growth of the aviation movement traffic there is need for change of classical approaches to the organization of flights for zone of airfield. Constant routes of the movement of air vehicles during implementation of landing maneuver are succeeded by replaceable landing paths which are defined by aircraft type and geographical conditions of airfield. In such conditions the existing systems of radio engineering providing need further improvement, as due to technical re-equipment, and application of modern methods of processing of signals. The purpose - improvements there has to be increase in accuracy of definition of the attitude of the airplane. Increases in accuracy and reliability of measurements of angular coordinates of the air vehicle in the azimuthal channel of the landing radar on condition of landing approach on free trajectories, by application of methods of optimum discrete filtering are task of this work. Advantage of such approach are applications for secondary processing of signals of well described, rather simple, mathematical algorithms what improvements of characteristics of accuracy of the landing radar without additional technical re-equipment are result of. Results of the carried-out modeling confirm functionality of the offered method and expediency of the chosen direction of research.
