Claims

[Scope of utility model registration request]

In a radar device consisting of an antenna that emits radio waves and a drive unit that rotates and raises the antenna, the drive unit drives a rotation axis using a motor mounted on the rotation unit to rotate the antenna, and also rotates the rotation axis around the rotation axis. Insert a bearing as a center into the pedestal part, insert a ring gear outside of this bearing, attach a grooved cam having vertically wavy grooves on the circumference to this ring gear with the rotation axis as the axis, and The driving part is provided with a gear that meshes with the ring gear via an electromagnetic clutch and an electromagnetic brake, while the rotating movable part is provided with a cam roller that rolls in the groove of the grooved cam, and the vertical movement caused by rolling in the groove of this cam roller is controlled. The antenna is configured to be connected via a connecting rod to the pivot of the antenna section provided at a position offset from the elevation axis on the swing section, and the antenna elevation drive converts the swing motion into vertical motion via a grooved cam and a cam roller. The radar is characterized in that the elevation angle is detected by an angle detector attached to the elevation axis, and the elevation and elevation of the antenna can be fixed or driven within a predetermined angle range by the electromagnetic clutch and the electromagnetic brake.
