Embodiment Construction
[0042]Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0043] A method for estimating and accurately tracking the satellite position of the reflector antenna proposed in this embodiment is different from the current communication antenna single-pulse self-tracking or program-guided tracking method, which is realized by controlling the mechanical axis of the antenna to perform conical scanning around the satellite The main steps are: drive the antenna to scan in azimuth and elevation respectively, record the angular position information of the antenna and the AGC voltage during the scan, and roughly estimate the satellite's approximate position; then the antenna control unit drives the antenna to point to the satellite's approximate position, and orbit Do conical scanning, according to the angle information output by...
