  • Optical image correlator tracking filter circuit
    Patent number: 4115801
    Abstract: A tracking filter circuit for use with optical image correlators is presented. The output signal of the optical image correlator exhibits a frequency content shift during operation due to the application of a ramp voltage to the nutation control circuitry of the correlator. The filter circuit is controlled by the ramp voltage such that the frequency response of the filter tracks the frequency content shift of the output signal. Integrator and multiplier circuits are interconnected as a part of a feedback network to accomplish the filtering technique.
