METHOD FOR DETERMINING LINEAR SPEED OF AIRCRAFT USING NON-RADAR INFORMATION

摘要

FIELD: measurement equipment.SUBSTANCE: linear speed of an aircraft is determined through projections of its vector to horizontal and vertical planes. At each k time moment there used is data that is supplied from a television system included in an optic electronic system and from a thermal direction finder included in the optic electronic system. Besides, current values of yawing angles of the aircraft and pitching angles of the aircraft are used at k and (k-1) time moments respectively. Angular speed of the change of the aircraft yawing angle ?and angular speed of the change of the aircraft pitching angle ?at k time moment is determined.EFFECT: improving measurement accuracy of linear speed of an aircraft using non-radar information.1 dwg
