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.

Projectile equipped with an infrared search system at its bow

A target detection method for a flying body provided with a search head, with the flying body rotating during its descending flight and scanning the area for possible targets, and in which the geometric dimensions of possible targets are determined in the scanning direction (Y direction) and in a direction perpendicular to the scanning direction (X direction) and are compared with corresponding stored values to determine the presence of a target. To avoid distortions of the scanned target in the Y direction, at least the angular velocity .omega. of the flying body, and preferably also the angle .phi. between the axis of rotation and the symmetry axis of the flying body, is continuously determined during the scanning process and, image correction values are calculated from the determined values and used to correct the geometric dimensions of the possible target in the Y direction.
