Abstract

PURPOSE:To make uniform the projective density of an antenna beam on the surface of the ground or the surface of the water by driving an antenna in the yaw direction and the pitch direction simultaneously. CONSTITUTION:In order to drive an antenna 33 mounted on a flying body 31 for searching a target object on the ground or the water while the flying body 33 flies, the antenna 33 is driven in two reciprocations in the pitch direction while it is driven in one reciprocation in the yaw direction. Under the condition that a beam radiated form the antenna 33 scans the surface of the ground or the surface of the water without any omission in searching, the density of projection 23 of the antenna beam can be made invariable substantially according to this method, without depending on the position of location of the target, and further an angular speed of the drive of the antenna can be made smaller than the one of usual antenna driving apparatuses.
