いるアンテナベデスタル装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an antenna vedestal device mounted on a ship and used in a moving object tracking device that uses microwaves to track other ships or aircraft.

Ｙ−ＡＺ−ＥＬ４軸マウント制御方式が行われてきた。Conventionally, when this type of antenna device is installed and used on a ship, it is necessary to provide a coupling relationship between each axis as shown in Figure 1b, which is a slightly more specific version of the schematic configuration in Figure 1a, to reduce the movement of the ship. X-

Although it has a simple principle of pointing the antenna in the target direction using an AZ-EL mount formed on the mount, it has the disadvantage that the structure is complicated and heavy due to multi-axis control. Furthermore, with regard to the mounting surface of the device, it is common practice to use the lower part of the device as the mounting surface, but this has the disadvantage that vibration resistance is low. In order to eliminate these drawbacks, the present invention has two features regarding the antenna.
The television camera is controlled in a three-way shape, and the pedestal is fixed to the mounting base at approximately the center thereof.

ew), we independently conducted it using HR koji. Since the specific means for controlling the attitude of only the antenna using these two axes {Fig. 3a} or three axes {Fig. 3b} is already known, detailed explanation will be omitted. 4a, b, and c are a perspective view, a front view, and a side view showing one embodiment of the present invention, in which 1 is an antenna section, 2 is an ITV

が向上できる。Further, 13 is a bedestal, and 14 is a motor for driving the HR axis of the television camera. In the figure, for ease of explanation,
AZ, EL, and HR direction lines and arrow lines indicating rotation are attached. The main components of this device are an antenna section 1, a television camera section 2, an Eu axis drive section 3, and an AZ axis drive section 11. It is fixed to the mounting base 5 by etc. The antenna section 1 and the television camera section 2 are arranged side by side on the EL ball 9 so that the weight balance around the AZ axis and the EL axis is maintained, and the EU axis 9 is connected to the EL axis drive section 3.
is fixed to the oath body via a bearing. Therefore, the antenna part 1
The center line (not shown), that is, the beam axis, and the HR line, that is, the optical axis of the television camera section 2 are parallel and always maintain a constant interval. However, since the antenna section 1 has a symmetrical shape with respect to the center line, even when the ship oscillates, only the center line of the AZ-EL module will be directed toward the target object, and therefore it is not suitable for practical use. However, in response to the rolling and pitching of the ship, the television camera unit 2 will capture the target as an image with its forehead tilted if it remains in the two-axis configuration, so it will accurately detect the target. need to be faced. In the present invention, the HR axis is made to coincide with the longitudinal direction of the weight body of the TV camera unit 2, and the TV camera body is rotated around the HR spindle to take a predetermined position by the HR koji drive unit stored in the TV camera case. . In this way, it becomes possible to capture the target object without tilting the mirror. As explained above, since the present invention is constructed with a maximum of three axes of AZ-EL-HR compared to the four-ball system, the foundation construction is simple, the weight is significantly reduced, and the control speed can be improved.
