Measurements of polarization characteristics of radiation field of on-board aircraft antennas
Abstract
A method for measuring the polarization characteristics of onboard antennas is analyzed in which an aircraft following an assigned trajectory is tracked from the ground and its angle of evolution with respect to the center of mass and the signal parameters at the output of the master antenna on the ground are measured. It is determined that rectilinear horizontal trajectories with no pitch or roll of the vehicle should be used. The requirements for the pitch and roll transducers must be made stiffer when selecting angle of measurement means; methods based on measuring amplitude ratios should be used when selecting a method for measuring the polarization characteristics of onboard antennas with arbitrary polarization.
