The first implementation：

The subreflector of the antenna is controlled to deflect predetermined angle towards the direction that the antenna is rocked, wherein, the angle-determining that the predetermined angle is rocked by the antenna；

Second of implementation：

Specifically, the directioin parameter that antenna is rocked is obtained in the present embodiment, specifically the directioin parameter that antenna is rocked can be detected by the direction rocked in antenna holding pole (or being fixed in the equipment of pole) placement gyroscope and accelerometer acquisition antenna and angle or by the method for software；The subreflector of antenna is controlled to deflect predetermined angle or skew preset displacement towards the direction, so that the opposite direction deflection in the direction that the sensing of antenna beam is rocked to antenna, compensation antenna rocks caused antenna radiation pattern and rocked, specifically it can deflect or offset towards the direction by the subreflector of voice coil motor (Voice Coil Motor, abbreviation VCM) or driving stepper motor antenna.Because VCM or stepper motor have the characteristics of being swift in response, and subreflector is lighter, therefore can quickly adjust the beam position of antenna, and compensation antenna is rocked.The angle-determining that above-mentioned predetermined angle is rocked by the antenna, the corresponding relation for the angle that the pre-set predetermined angle of empirical value is rocked with antenna can draw according to, or adaptively drawn according to the change of directioin parameter by antenna itself；The angle-determining that above-mentioned preset displacement is rocked by the antenna, the corresponding relation for the angle that the pre-set preset displacement of empirical value is rocked with antenna can draw according to, or adaptively drawn according to the change of directioin parameter by antenna itself.
