TARGET-RECOGNITION PROCEDURE FOR MISSILES THAT INCORPORATE A SEEKER HEAD

摘要

The present invention relates to a target-recognition procedure for a missile with a seeker head, the missile rotating as it falls to Earth, while scanning the ground for possible targets. The geometrical dimensions of possible targets in the direction of the scanning track (Y-direction) and in the direction perpendicular to the scanning track (X-direction) while taking into account the distance r between the missile and possible targets are determined and compared with corresponding stored values. In order to avoid any distortion in the Y direction of the target that has been scanned, the invention proposes that the angular velocity .omega. of the missile and the angle .PHI. between the axis of rotation and the axis of symmetry of the missile be determined continuously during the scanning process and image correction values with which a correction of the geometrical dimensions of the possible target in the Y direction can be made be computed from these values.
