Abstract : The patent describes an angle data processor apparatus using a pair of phase-locked oscillator to determine the phase difference between transmitted reciprocating scanning beams. The phase difference is displayed to provide glide angle information. The present invention relates broadly to an aircraft landing system and in particular to a microwave landing system for determining aircraft glide angle during landing.
