Abstract:

The patent relates to a tracking filter apparatus for determining the relative phase of synchronized CW navigation systems. The apparatus generates a square wave signal the phase and amplitude of whose fundamental sinusoidal components match those of the fundamental components of signals being tracked. The apparatus operates with a digital computer which processes sample OMEGA amplitudes to acquire and maintain synchronism with the standard OMEGA multiplex pattern.
