Scale model pattern measurements of aircraft L-band beacon antennas
Abstract
The techniques and apparatus used to measure the directional patterns of aircraft ATC transponder antennas (L-band) with digital techniques and to store the data on magnetic tapes were described. Algorithms involved in data normalization, cross-polarization correction and coordinate conversions are discussed. Some typical applications of the data are illustrated with actual computer outputs obtained from the scale model measurements.
