Boeing-Duluth has developed and demonstrated a high performance laser fire control system (HPFCS) capable of acquiring, tracking, laser rangefinding and designating incoming projectile and missile threats within a 0.5 second timeline. The demonstration fire control system has a hemispherical field-of-regard and is comprised of a longwave infrared threat warning system and a high performance laser pointing system. The threat warning system includes a longwave infrared sensor, a system processor and target acquisition and tracking software. The demonstration pointing system consists of: (1) a stabilized platform; (2) an infrared sensor package containing two narrow FOV passive tracking cameras, a four quadrant laser rangefinding sensor, a narrow FOV laser spot tracking camera, and a Nd:YAG laser designator; (3) the platform digital control electronics; (4) a system control computer; (5) the platform control software; and (6) the acquisition, tracking and pointing (ATP) software. The pointing system has been designed with 10,000 degrees/sec2 to perform a 90 degree slew in less than 0.2 seconds to engage a 1000 m/s projectile launched from 1000 meters and 45 degrees off boresight. In addition, the modular off-gimbal design can accommodate various sensor systems from the visible to the infrared with apertures up to 5.5". The HPFCS has demonstrated all fire control system ATP functions against simulated mortar targets.
