A semiballistic projectile system is disclosed. The system includes a semiballistic projectile ground tracking and rangefinding system that selectively transmits course correction and rangefinding signals. The semiballistic projectile has a pyroelectric detector that includes a reflecting portion, nonreflecting portion, and a focusing lens for focusing electromagnetic signals onto the pyroelectric detector adjacent to its periphery. The reflecting port ion operates by reflecting impinging electromagnetic signals as return signals for orienting course corrections and the nonreflecting portion receives and decodes coded course correction signals for a jet thrust or other steering apparatus which corrects the projectile\s course to a target.
