According to the drive device 1200 as described above, when the drive source 1211 is operated, the rotational power thereof is transmitted to the frame 1100 through the first and second drive bodies 1212 and 1213. Accordingly, the frame 1100 rotates. In this case, the frame 1100 may be adjusted to the first to fourth angles θ ₁ to θ ₄ as shown in FIGS. 2 to 5 according to the operation size of the driving source 1211. That is, the frame 1100 has a first angle (θ ₁ = 0°) as shown in FIGS. 2 and 6(a), and a second angle (θ ₂ = 15°) as shown in FIGS. 3 and 6(b) , It can be adjusted to a third angle (θ ₃ = +90°) as in FIGS. 4 and 6 (c) and a fourth angle (θ ₄ = -90°) as in FIGS. 5 and 6 (d). have.

For example, when the installation part 120 is inclined by 15°, at least some of the areas excluding the edge of the first installation surface 121 of the installation part 120 are recessed in the direction of the second installation surface 122 It can be pitted. Accordingly, each of the first installation surface 121 and the second installation surface 122 is not flat. Accordingly, a plurality of antenna elements 110 installed on each of the first and second installation surfaces 121 and 122 may not be flat.

In addition, in a state in which the plurality of antenna elements 110 are flatly arranged, when all the transmission signals transmitted from the plurality of antenna elements 110 are radiated under the same condition, or all reflected signals are processed under the same condition, the target Position, movement trajectory, movement speed detection performance may be degraded.

That is, the frame 1100 is rotated to become a second angle θ ₂ , so that the antenna device 100 mounted on the frame 1100 becomes a second angle θ ₂ . Then, in a state in which the antenna device 100 is at the second angle θ ₂ , the state of the antenna device, that is, the flatness is checked in advance. In addition, the transmission signal may be corrected and emitted by reflecting the confirmed or detected flatness, or the reflected signal may be corrected to improve the tracking performance or accuracy of the target.
