Claims

[Scope of utility model registration request]

In a radar device comprising an antenna that emits radio waves and a drive unit that rotates and raises the antenna, the drive unit drives the rotating movable unit with a motor fixed to a pedestal,
While rotating the antenna, a ring gear attached via a bearing inserted in the rotating movable part and a grooved cam having vertically wavy grooves on the circumference are driven at a speed different from that of the rotating movable part, On the other hand, a cam roller that rolls in the groove of the grooved cam is installed in the movable swivel part, and the vertical movement caused by rolling in the groove of this cam roller is connected to the pivot of the antenna part that is located on the swivel part at a position offset from the elevation axis. A radar characterized in that the antenna is configured to be connected via a rod, and the antenna elevation drive is performed by vertical movement converted via a ring gear and grooved cam and a cam roller that convert rotational movement into different speeds.
