Abstract
A system for tracking a projectile utilizing a laser beam modulated by an acousto-optic cell. Transponders distributed on hemispheres around the rear of the projectile detect the scanned beam and actively transmit a narrow optical beam back to a ground-based receiver in response to a detection of the scanned beam. IFF information can be modulated onto beam actively transmitted from the transponder. The system provides active two-way communications with comparatively simple components.
