A two-axis antenna overhead method
An antenna azimuth and antenna technology, applied in the direction of the antenna, electrical components, etc., can solve the problems that the two-axis antenna cannot meet the tracking and communication requirements, the antenna cannot complete the tracking task, and the pitch axis angle cannot exceed 90 degrees, and achieves a high level of improvement. Tracking capability, meeting tracking and communication requirements, effect of reducing rotational speed

Embodiment Construction
[0036] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0037] A two-axis antenna over-the-top method, in the structure design of the antenna, compared with the traditional two-axis antenna, the pitch axis rotation range is designed to be 0-180 degrees. According to the target satellite information and the position and attitude changes during the movement of the carrier, the method calculates the pointing angle of the antenna in real time, and judges whether the difference between the azimuth target deck angle and the current deck angle is too large. Based on this, different tracking methods are adopted. In this way, the range of azimuth rotation is reduced, the speed and acceleration of azimuth rotation are reduced, and the tracking ability of the two-axis antenna is improved. refer to figure 1 , the specific top method is:
[0038] 1) According to the target sa...
