摘要：<p>PURPOSE:To obtain the synchronous rotation system for the nearby antennas by providing antenna controllers which controls servomotors for rotating the antennas and providing a means which controls one of the two antenna controllers. CONSTITUTION:An angle instruction generator 7 generates an angle signal synchronized with the rotation of the antennas 5a and 5b of a radar and supplies angle instructions 6a and 6b to the antenna controllers 1a and 1b. Then respective airport detection radars ASDE receive the instructions 6a and 6b and rotate the antennas 5a and 5b of the radar synchronously. Here, the controllers 1a and 1b and antennas 5a and 5b form servo loops and hardly have errors between the instructions 6a and 6b and the actual angles of the antennas 5a and 5b. Therefore, the antennas are rotated synchronously as long as the generator 7 generates the synchronous angle instructions. Then even when there are >=3 angle instructions, the phase difference of the signals generated by the generator 7 is selected properly and even at the time of an ASDE and other radars, the rotating speed and phase difference of the signals are selected properly to preclude mutual disturbance.</p>
