Abstract
A method and system for monopulse beamforming for electronically switched antennas is presented. Inputs of selected antenna elements from a phased array antenna are summed into subsets of elements which are then combined into sum and delta beams. 2:1 switches in a shoelace arrangement allow the combination of signals from half of the selected aperture first at common phase and then at pi phase difference to from the sum and delta beams. The method allows for reduced weight, controls, and processing when compared to prior art.
