An improved missile guidance system is provided which automatically compensates for jitter motion of the optical sight of a video tracker. The invention is adapted to receive video data input from an infrared detector or conventional camera. The invention includes circuits for filtering, gating, and digitalizing the incoming data as well as a formatter for directing successive frames into memory. Two memories are provided; the contents of which are sampled by matching logic as the second memory is being loaded. The matching logic thereby compares one frame of data to another at plurality of positions and provides a signal to an address latch when the best match is obtained. The format circuitry provides the position information to the address latch where it is stored for further processing. The output of the address latch is filtered to eliminate any signals representative of intentional tracking motion. The filtered output thus provides the jitter correction to the missile guidance system where missile guidance signals are compensated by the jitter correction.

In a missile guidance system including tracking means and means for providing first signals for guiding a missile to a target, an improvement comprising: means for providing successive frames of data corresponding to at least a portion of a video scene as viewed by said tracking means; means for analyzing said frames of data and providing second signals indicative of jitter motion of said tracking means relative to said video scene; and means for compensating said first signals as a function of said second signals to provide signals for effectively guiding said missile notwithstanding any jitter motion of said tracking means.
