A missile guidance system having means for deriving from a target angle tracking loop a signal indicative of an apparent movement of a target off a missile-to-target sight line caused by a change in missile attitude, and means for feeding said apparent movement signal into a space stabilization loop to adjust the position of the aerial to compensate for said apparent movement.

Tracking radar systems

A phase-lock loop system with particular use in radar tracking systems is disclosed. From a number of input signals of varying frequencies such as a carrier frequency and several side band frequencies the system can lock into phase and frequency with the input which has the largest amplitude by sweeping across a predetermined range of frequencies and allowing the phase-lock loop to operate only when a predetermined amplitude is exceeded.
