Claim One:
1. A tracking system for determining the relative location of a designated target comprising: sensor means for providing received video signals that are indicative of the intensity of received infrared energy and for providing sensor position signals indicative of the relative position of said sensor means; a gated video processor responding to the received video signals for providing digital target signals representative of the image area of targets, said processor having a gate signal input circuit; gated video tracking means responding to the target signals for generating target position signals indicative of the relative location of a designated target, said gated video tracking means having a plurality of tracking gate input circuits; and gate generating means, responding to said target position signals and to said sensor position signals, for applying a plurality of tracking gate signals to said plurality of tracking gate input circuits and for applying processor gates to said gate signal input circuit of said video processor.
