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.
