<p>PURPOSE:To remove a useless reflected signal from the ground by receiving and synthesizing the output of an antenna element, generating an optimum pattern as a side lobe blanker by means of a controller and giving a transmitting phase and an attenuation quantity to the antenna element. CONSTITUTION:An antenna beam angle signal 8 and a flying body action signal 9 are inputted to the controller 4, which controls the transmitting phases and attenuation quantities of the antenna elements 51-5m. A reception signal synthesizer 6 synthesizes the reception signals of the antenna elements 51-5m, which are used as a SLB channel 7. If the antenna beam of the main channel of an electronic control antenna orients an angle shifted by an angle theta1 with respect to a central axis 13, the beam pattern 141 of the main channel turns to be the beam pattern 161 of the SLB channel corresponding to a reflected signal from the surface ground 15 by means of the side lobe. Where the beam orienting direction of the antenna of the main channel is shifted by an angle theta2 with respect to the central axis 13, a pattern 162 with respect to a ground reflected signal is generated.</p> |
