Abstract : The patent describes a system for measuring angular velocity by comparing the frequencies of oppositely-directed microwave signals. In one embodiment, a gyro is disclosed in which a circular waveguide loop is used and oppositely directed signals are read out separately for comparison of their frequencies and phases. Angular velocity of the gyro about an axis perpendicular to the plane of the loop results in a difference in frequency between the two output signals. The difference in phase between these signals, being proportional to the time integral of the frequency difference, is thus proportional to the angular position of the gyro.
