Background
The phased array antenna is an antenna which changes the shape of a directional diagram by controlling the feeding phase of a radiation unit in the array antenna, and the control phase can change the direction of the maximum value of the directional diagram of the antenna so as to achieve the purpose of beam scanning, namely the adjustment of the inclination angle of the array surface of the phased array antenna. Compared with the traditional mechanical scanning antenna, the inertialess high-speed scanning of the wave beam is realized by adopting electronic phase shifting, the direction of the electromagnetic wave beam is flexibly controlled, the tracking speed is high, and the real-time high-precision satellite alignment of the antenna under the high-speed moving condition can be ensured; the rapid and rapid change of the electromagnetic wave polarization is realized through electronic phase shifting, the real-time matching of the antenna polarization and the polarization of a tracking satellite can be ensured, and the continuous and reliable satellite communication capability is provided for installed vehicles; in addition, the electric scanning phased array antenna also has the technical characteristics of low section, light weight, easy installation and the like, and does not need any mechanical servo system which is easy to wear.
At present, when a beam of an existing electric scanning phased array antenna is scanned to a large-angle direction, the problems of rapid reduction of scanning gain, deterioration of cross polarization and the like can occur, and the scanning angle range of the electric scanning phased array antenna can only reach +/-60 degrees under a common condition, so that omnibearing scanning cannot be realized. Therefore, the limit of the scanning range of the conventional phased array antenna is broken through, the coverage of a large-angle high-gain wave beam of the antenna is realized, and the phased array antenna is an important technical support of a vehicle-mounted satellite-borne phased array antenna. Related documents combining a mechanical servo control system with a phased array antenna exist in the prior art, for example, chinese patent No. CN113219873A discloses a phased array antenna motion control apparatus and a control method thereof, which implement non-blind area scanning by combining mechanical adjustment of a mechanical execution unit with phase adjustment of a phased array antenna main body.
However, in the existing technology combining mechanical adjustment and phase adjustment, phase adjustment needs to be realized according to feedback information after the mechanical adjustment is completed, which results in that the time length for tilt angle adjustment control of the whole phased array antenna is prolonged, and the amplitude fluctuation of the mechanical adjustment is large under the high-frequency and large-range scanning application environment, which is not beneficial to timely, stably and accurately completing scanning of the phased array antenna; in addition, the existing technology combining mechanical adjustment and phase adjustment has complex treatment logic in the implementation process, and is not beneficial to flexibly adjusting the inclination angle of the whole phased array antenna according to the actual situation.

In addition, the error correction angle can be adjusted by adopting a preset value, and can also be obtained by carrying out comprehensive analysis according to the cooperative coefficient, the rotating speed and the time length controlled by the mechanical control platform. For example, the error correction angle is positively correlated with the rotation speed alone, the time length alone, or both.
