Feasibility of Offset Carrier Systems for Air Traffic Control.

Abstract

A review of offset carrier systems development and history is provided for insight into problems that can affect air traffic control. An amplitude modulated offset carrier system is discussed as a special case of normal AM superheterodyne communications. Potential problems of heterodyne beats that can occur above, below and in the audio band are noted. Potential audio phase delay distortion between two or more signals is discussed with respect to remote control line problems are to differential propagation delay problems. The difficulty in combining audio from separate remote receivers is discussed. Target acquisition model contours are provided for the four air traffic sectors to be used in the remainder of the study. (Author)
