Abstract

A guidance system for deployment on-board a projectile includes a laser-seeking detector, an imaging device, and a control module. The laser-seeking detector is designed to detect the position of the projectile with reference to a laser spot on a target. The imaging device is designed to capture one or more images in front of the projectile. The control module is designed to control a flight direction of the projectile based on input received from the laser-seeking detector in a first mode, control the flight direction of the projectile based on input received from the imaging device in a second mode, and switch between the first mode and the second mode while the projectile is in flight towards the target. Both guidance technologies are leveraged to develop an improved guidance technique that provides highly accurate targeting and allows for a faster rate of fire to deal with multiple targets.
