Abstract.
At the solution of problems of air traffic control and
guidance of aircraft it is necessary to carry out monitoring of surrounding
space. The most important problem of monitoring of air space is estimation of
coordinates and parameters of the movement of air objects which is carried out
by the onboard radar-tracking system which is a part of the integrated
radio-electronic complex of the aircraft. Efficiency of functioning of a radio-electronic
complex of the aircraft in the modes providing air traffic control and
formation of teams of guidance of the aircraft depends on quality and
reliability of the solution of this task in essential degree. For creation of
effectively functioning systems of trajectory maintenance which realization
demands application of complex information processing, it is necessary to have
functionally connected mathematical models of coordinates and parameters of the
movement of air objects and model of supervision. Thus an important role when
developing mathematical models is played by a choice of system of coordinates.
Rather often and guidance of the aircraft applies beam system of coordinates to
control systems of air traffic. The advantage of the coordinate system is that
in it the airborne radar tracking system directly performs measurements of the
range to the air object, the speed of approach to it and its angular
coordinates. Besides, at guidance of aircraft of various types rather
often parameters of management are formed in beam system of coordinates. In
the article joint mathematical models of the relative and absolute movement of air
objects are given in beam system of coordinates and the corresponding
mathematical models of supervision used at the solution of problems of
estimation of coordinates and parameters of the movement in an onboard
radio-electronic complex of the aircraft at maintenance of air objects.
Features of creation of algorithms of trajectory maintenance with use of these
models providing with necessary information of a control system of air traffic
and guidance of aircraft on air objects are specified.
Keywords:
mathematical model, beam system
of coordinates, relative and absolute movement, aircraft, air object,
