Coordinate determination errors in measuring characteristics of radiation field of airborne antennas
Abstract
Expressions are derived for estimating the coordinate errors in measuring the characteristics of the radiation field of airborne antennas. Errors in six coordinates must be taken into account at any given moment: the azimuth, elevation, slant range, heading, pitch and roll of the aircraft. It is recommended that straight-line flights be employed. Maneuvers should be used only in extreme cases, such as for measurements in the upper hemisphere. Conditions are specified under which it is possible to measure the characteristics of airborne antennas not equipped with maneuvering sensors, recording means or telemetry.
