Fourier transform techniques have been applied to measure image velocity and position. These patented techniques have been incorporated into airborne image motion compensation sensors, helicopter-borne image stabilizers, and TV trackers for tank and helicopter fire control. Microradian tracking accuracy at less than 5-percent contrast has been demonstrated with simpler and less costly hardware than required with correlation techniques.
