ABSTRACT:
A target scanning system for radiation seeking guided missiles. Radiation incident on a Cassegrainian reflector system images at a focal point on a primary optic axis. The Cassegrainian reflector system produces a first scanning pattern and diverts it to a tertiary reflector. The tertiary reflector has its reflective face canted from its spin axis to produce a second scanning pattern. The two scanning patterns combine to produce the desired rosette scan that is scanned over a sensor.
