ABSTRACT:
VOR receiver which operates in known manner when receiving from normal VOR ground stations, SSB-DVOR and DSB-DVOR ground stations, and with substantially improved accuracy when receiving ASB-DVOR ground stations. When the receiver receives ASB signals, one sideband is suppressed, and the phases of the half-wave-shaped signals present after demodulation of the other sideband are measured. The azimuth is determined from the measured phase values of each complete antenna cycle by Fourier integration.
