Arbitrary spatial filters based on beam transformation

Abstract

Systems and methods for operating phased arrays are described. A circuit can receive an index associated with an antenna among a plurality of antennas in a phased array. The circuit can use the index to identify at least a phase value and a gain value of a known beam. The circuit can receive at least one static configuration of the antenna and at least one beam transformation parameter. The circuit can transform, based on the at least one beam transformation parameter and the at least one static configuration, the phase and gain values of the known beam into phase and gain values of a desired beam. The circuit can map the phase value of the desired beam to a phase shifter setting of the antenna and the gain value of the desired beam to a variable gain amplifier setting of the antenna to generate the desired beam.
