Abstract:
1. A weapons system including a laser-guided projectile, said guided projectile comprising a semi-active laser (SAL) seeker including receiver optics that capture and direct pulsed-laser electro magnetic radiation (EMR) scattered from a target to form a laser spot on a detector assembly, said assembly comprising one or more detectors each producing a signal in response to the laser power incident thereon, a signal processor and a first portion of computer-readable program code loaded into signal processor memory and executed by the signal processor to process the one or more signals to output a designator code and one or more guidance signals indicative of the position of the laser spot on the one or more detectors and the bearing to target, wherein the improvement to the weapons system comprises: a communication device that generates a pulsed optical beam that overlaps the detection band of the one or more detectors, said pulsed optical beam encoded with data for the SAL seeker; and a second portion of computer-readable program code loaded into signal processor memory and executed by the signal processor to process the signals to extract the data for the SAL seeker.
