Abstract
A method is provided of generating a course-correction signal for a spin-stabilized projectile. The method includes capturing a time-sequence of images of a scene at a frame rate, comparing respective current images of the time-sequence of images to a corresponding previous image of the time-sequence of images, determining a rotation angle between the current and previous images, rotating the images using the rotation angle, identifying a target in the rotated images, generating target bearing angles to cause the projectile to correct its course toward the target using the target bearing angles, and adjusting the target bearing angles to compensate for the rotation of the images.
