A retro reflection guidance and control system for a projectile, and a method of obtaining flight characteristics and controlling the projectile. A launch platform based transmitter/receiver and processor sends signals to a projectile, which signals are received at the back thereof. The transmitted signals are selectively reflected, to provide flight characteristic information to the transmitter/receiver, and detected to provide flight control information to the projectile.

Apparatus for obtaining flight characteristics of and controlling a rolling projectile, said apparatus comprising: a transmitter/receiver located on a platform and adapted to transmit signals and to receive signals; guidance command signal computation means on said platform and coupled to said transmitter/receiver; and signal receiving means on said projectile, said signal receiving means being accessible to transmitted signals from said transmitter/receiver, said signal receiving means comprising: collecting lens means at one end of said projectile; a reticle having normally reflective and normally transmissive segments in a predetermined pattern, said reticle being positioned inwardly from the externally exposed surface of said lens means; said reticle being positioned off of the projectile roll axis, with its optical centerline positioned at an angle with respect to the projectile roll axis; and detector means positioned inwardly of the exposed surface of said lens means and adapted to detect signals transmitted through said lens means and not reflected by said reflective segments of said reticle; whereby said computation means provided information as to roll rate, roll phase and pitch attitude of said projectile.
