Abstract
Provided are a method, phased array system, and integrated circuit for calculating phase and gain parameters to control antennas for a specified spatial filter. Front-end units receive weights, and phase slope parameters for component beams. A front-end unit of the front-end units calculates a phase shift and gain parameters for an antenna controlled by the front-end unit based on the phase slope parameters, the weights, and a physical location of the antenna controlled by the front-end unit.

A method of operating a phased array, comprising:
- receiving, at front-end units, weights, and phase slope parameters for component beams;
- and
- calculating, at a front-end unit of the front-end units, a phase shift and gain parameters for an antenna controlled by the front-end unit based on the phase slope parameters, the weights, and a physical location of the antenna controlled by the front-end unit.
A phased array system, comprising:
- a plurality of antennas;
- a plurality of front-end units for controlling the antennas;
- a spatial filter generator for:
- determining weights and phase slope parameters for component beams;
- and
- transmitting the weights and the phase slope parameters to front-end units controlling antennas;
- and
- logic implemented in the front-end units, wherein the logic implemented in a front-end unit of the front-end units calculates a phase shift and gain parameters for an antenna controlled by the front-end unit based on the phase slope parameters, the weights, and a physical location of the antenna controlled by the front-end unit.
An integrated circuit for controlling antennas in a phased array, comprising:
