Abstract: A system includes a target illumination laser (TIL) (210) configured to illuminate an airborne target (120, 240) with a TIL beam (235). The system also includes a beacon illuminator (BIL) (215) configured to transmit a spot of illumination (245) to an expected location on the target, where the spot of illumination is more focused than the TIL beam. The system further includes a camera (220) configured to receive an image of the spot reflected off the target. In addition, the system includes a controller (230) configured to determine an actual location of the spot on the target based on the received image. The controller is also configured to estimate a spot motion by correlating the actual location of the spot on the target with the expected location on the target. The controller is further configured to predict uplink jitter (316) of a high energy laser (HEL) beam generated by a HEL (205) based on the BIL spot motion, where the uplink jitter is caused by atmospheric optical turbulence (238).

Abstract: A system includes a high energy laser (HEL) (205) configured to transmit a HEL beam (322) aimed at a first location on an airborne target (240). The system also includes a beacon illuminator laser (BIL) (215) configured to transmit a BEL beam (320) aimed at a second location on the target, wherein the second location is offset from the first location. The system also includes at least one fast steering mirror (FSM) (302, 304) configured to steer the BIL beam to be spatially and angularly offset from the HEL beam. The system also includes at least one Coudé path FSM (312, 314) configured to simultaneously receive both the HEL beam and the BIL beam and steer the HEL beam and the BIL beam to correct for atmospheric jitter of the HEL beam and the BIL beam while maintaining the offset of the BIL beam from the HEL beam.
