Systems and methods for reducing directional interference based on adaptive excision and beam repositioning

摘要

Systems and methods are provided for repositioning a directional antenna that responds to a desired signal and directional interference. The antenna can generate a sum beam and first and second difference beams. Respective powers of the sum beam and the first and second difference beams can be determined. At least a portion of any of the directional interference can be excised from the sum beam and the first and second difference beams. Measures of the directional interference can be determined in the sum beam and the first and second difference beams. A first correlation between the sum beam and the first and second difference beams can be generated. Additional correlations between a signal identifier and the sum beam and first and second beams monitor the desired signal reception. The antenna can be repositioned away from the directional interference based on the powers, the measures, and the first correlation.
