Automatic satellite aligning method and device for phased array antenna

Abstract

The invention discloses an automatic satellite aligning method and device for a phased array antenna. The method comprises steps: the attitude angle of an antenna carrier, the latitude and the longitude of a phased array antenna carrier, the height, the target satellite longitude and the height are acquired, and conversion between an antenna carrier coordinate system and a geodetic coordinate system at any position is completed; in the antenna carrier coordinate system, the beam pointing of the phased array antenna is calculated, and the phased array antenna is controlled to point to the satellite; an acquired satellite aligning locking indication signal and a signal power value under the beam pointing are received, and conical scanning is adopted for beam pointing adjustment; whether to capture a satellite successfully is judged, a beam pointing angle corresponding to the maximum power value in a locking indication signal effective condition is found out, and the phased array antennais controlled to complete beam pointing switching; and based on the beam pointing, next conical scanning is carried out. The phased array antenna can be quickly aligned with the target satellite at any place, the effects of simple and convenient satellite aligning are achieved, and the method and the device can be widely applied to a satellite communication system.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and relates to a method and a device for automatic satellite alignment of a phased array antenna. Background technique [0002] With the continuous advancement of science and technology, satellite communication has become a major communication method in today's society. Satellite communication equipment plays an important role in the fields of public emergency handling, emergency command, and real-time information transmission. [0003] For traditional servo antennas, the beam pointing and scanning mainly depend on the control of mechanical servo, and the beam switching time is slow, which makes it impossible to achieve fast tracking of the target. The phased array antenna adopts the electronic scanning method, which can quickly respond to beam switching, and can quickly complete multi-angle scanning in the airspace, so as to realize the advantages of fast tracking of targets and ...
