| 摘要 | PURPOSE:To enable searching and tracking of a target to be accomplished simultaneously with simple constitution by using a fan beam for the beam to be radiated from an antenna, and so constituting the system that this fan beam is rotated. CONSTITUTION:When the movable terminal 8a of a switch 8 is changed over to the stationary terminal 8b side, the transmitted electric power radiates a fan beam 1 from an antenna 2 to targets A, B, and the reflected echoes thereof input to an indicating device 3 and a tracking device 6 via a transmitter-receiver 4. In the tracking device 6, the received echoes and the rotation angle signal of the antenna 2 are compared and the error signals of angle of elevation and azimuth are transmitted to an antanna driving part 7, by which the bearing and the angle of elevation are changed while the antenna 2 is being rotated in the direction of an arrow a1. Next, in the case of operating this as a search radar system, the movable terminal 8a of the switch 8 is changed over to the stationary terminal 8c side. The antenna 2 rotates in the arrow a3 direction around the y-axis, and this system serves as a search radar. In this way, the searching and tracking are accomplished simultaneously with the simple constitution. | ||||||
