[0003] In the prior art, sector level sweep (sector level sweep, SLS) is the main part of array antenna beamforming technology, usually, sector level sweep includes transmit sector level sweep, receive sector level sweep, sector sweep There are 4 parts, including feedback and sector scanning confirmation. Sector scanning needs to traverse each antenna of the device and each sector of the antenna. In the feedback and confirmation of sector scanning, it may not be received due to interference or noise. need to resend
Therefore, in the process of sector-level scanning, the number of information interactions is very large, and these information interactions account for the main part of the beamforming technology, which greatly increases the time loss of the beamforming technology and reduces the efficiency of the beamforming technology

The invention discloses an array antenna beam forming method and system. The position of a second device is fixed, and a locating signal is transmitted to a first device through a locating apparatus arranged on the second device to determine relative position information between the two devices; main beam constraint conditions between array antennas of the two devices are separately determined according to the relative position information between the two devices; and beam forming is performed according to the main beam constraint conditions to obtain a beam satisfying the main beam constraint conditions. According to the array antenna beam forming method and system disclosed by the invention, the main beam constraint conditions necessary for beam forming are directly determined according to the relative position information between the devices, therefore the information interaction times during beam forming can be reduced, the time loss of the beam forming can be reduced, the beam forming establishment time is shortened, and the beam forming efficiency is improved.
Description
technical field [0001] The present invention relates to the technical field of beam forming, in particular to an array antenna beam forming method and system. Background technique [0002] Array antenna is a technology that uses the spatial difference of different signal transmission and array digital signal processing, which can distinguish and isolate different target signals from the perspective of airspace, so as to reduce multiple access interference, increase capacity, expand coverage, and improve communication. The purpose of improving quality, reducing transmit power and increasing wireless data transmission rate. [0003] In the prior art, sector level sweep (sector level sweep, SLS) is the main part of array antenna beamforming technology, usually, sector level sweep includes transmit sector level sweep, receive sector level sweep, sector sweep There are 4 parts, including feedback and sector scanning confirmation. Sector scanning needs to traverse each antenna of...
