The wind profile radar adopts a phased array antenna structure, the size of an antenna array surface is large, and the whole wind profile radar cannot be transported generally. In order to meet the transportation requirements, the antenna array is divided into a plurality of antenna array units, and the antenna array units meet the transportation requirements.

The common antenna bracket only has a small distance adjusting range, and has poor leveling precision and time-consuming leveling under the conditions of large antenna array surface and large ground fluctuation. For example, when the distance that a certain fulcrum needs to be adjusted exceeds the adjustment range of the antenna bracket, if the height of the fulcrum of the antenna bracket is lower than the height of the adjusted fulcrum, the height of the fulcrum of the antenna bracket can be reduced by adopting a method for reducing the heights of the fulcrums of other antenna brackets with the adjusted heights; if the height of the antenna support fulcrum is higher than the height of the adjusted fulcrum, the field generally does not damage the antenna support, and at the moment, the problem can be solved only by increasing the heights of the other antenna support fulcrums with the adjusted heights. No matter the height of the supporting point of the antenna bracket is higher or lower than the height of the adjusted supporting point, when the distance that the supporting point needs to be adjusted exceeds the adjusting range of the antenna bracket, the supporting point with the adjusted height needs to be adjusted again, so that the situation that the height of the adjusted supporting point is repeatedly adjusted occurs, and the time is very consuming.

The threads at the two ends of the double-head screw rod 1-2 are self-locking trapezoidal threads, the lead is larger, and the distance of the upper supporting leg 1-1 moving up and down relative to the lower supporting leg 1-3 is larger due to one-circle rotation of the double-head screw rod 1-2, so that the double-head screw rod is used for rough adjustment of the leveling of the antenna array surface unit 6.
After the antenna array is leveled, the rough adjustment handle 4 may be removed from the leveling mechanism 5.
As shown in figure 4, the movable support 2 consists of a support bottom plate 2-1, a support reinforcing rib 2-2 and a support top plate 2-3. The upper end of the support reinforcing rib 2-2 is provided with a support top plate 2-3, and the lower end is provided with a support bottom plate 2-1. The support base plate 2-1 is provided with a support base plate mounting hole 2-1-1 which is connected with an upper support leg top plate 1-1-1 of the upper support leg 1-1 through a fine adjustment bolt 3.
As shown in fig. 5, the wind profile radar antenna array consists of several antenna array elements 6.

As the diameter of the upper end thread of the fine adjustment bolt 3 is smaller than the diameter of the support base plate mounting hole 2-1-1 of the support base plate 2-1, a gap is formed between the upper end thread and the support base plate mounting hole 2-1-1, and the gap ensures that the upper end of the fine adjustment bolt 3 can rotate and incline relative to the support base plate 2-1, so that the support base plate 2-1 can incline relative to the upper support leg top plate 1-1-1.
