Patent ID: 8632338

Claim:
A target acquisition apparatus, for use in association with a moving target, the moving target including a modulated light emitter assembly, the modulated light emitter assembly including a plurality of light emitters arranged in a predetermined spatial configuration and emitting invisible light radiation and modulated according to a predetermined modulation characteristic, the modulation characteristic being unique for the moving target, said target acquisition apparatus comprising: a weapon activation sensor, to be coupled with a weapon, for detecting activation of said weapon and producing a triggering signal; an image detector, for acquiring an image of at least a portion of said moving target, in response to said triggering signal, a line of sight of said image detector being aligned with an aiming direction of said weapon; a modulated light detector, for detecting said light radiation, the modulated light detector line of sight of said modulated light detector being aligned with the aiming direction of said weapon; a weapon processor, coupled with said weapon activation sensor, said image detector and said modulated light detector, said weapon processor identifying said predetermined modulation characteristic from said detected light radiation, identifying said predetermined spatial configuration within a predetermined portion of said acquired image, determining a local coordinate system defined by said light emitters, and producing a hit indication in response to coinciding occurrence of said predetermined modulation characteristic identification and said predetermined spatial configuration identification; and a weapon transceiver, coupled with said weapon processor, for transmitting said hit indication.
