Abstract

PURPOSE:To control a directivity in a vertical in-plane and to attain the automatic tracing by providing a control means to move a relative position of a main reflection mirror and a primary radiation system in a vertical direction and control the directivity in the vertical in-plane. CONSTITUTION:An electric wave radiated from a primary radiation system 2 is reflected by a main reflection mirror 1 and radiated non-directionally in a horizontal direction. When a relative position if the main reflection mirror 1 and the primary radiation system 2 is moved in a vertical direction by a control means 3, for example, a phase center (a) of the primary radiation system 2 is coincident to the focus of the main reflection mirror 1 and the characteristics of a vertical in-plane directivity, in which the horizontal direction is maximum are held, the primary radiation system 2 is moved in the vertical direction, the phase center is moved to a' as shown by the dotted line by the control means 3, and then, the vertical in-plane directivity, in which is in the upper direction only by from the horizontal direction. Thus, the non-directivity is obtained in the horizontal surface, the maximum sensitivity is always obtained, and thus, the control means 3 is controlled, a vertical in-plane directivity is controlled and the automatic tracing function can be realized.
