ABSTRACT:
A projectile equipped with an infrared target seeking system at its bow and an arrangement for correcting the flight course of the projectile, with the target seeking system having at least one deflection device for scanning the target area. To obtain a rosette-shaped scanning pattern of the target area without the use of gyro stabilized mechanical systems, the projectile rotates about its longitudinal axis and the target seeking system includes a laser which is followed by a beam deflecting device which deflects the laser beam periodically and linearly within a fixed scanning plane passing through the longitudinal axis of the projectile. Preferably the laser beam is also amplitude modulated.
