Abstract:
A method of phased array antenna beamforming comprising the steps of:receiving an incoming electrical wavefront by an antenna, said electrical wavefront having a phase front at a wavefront phase angle; generating a local oscillator wavefront, said local oscillator wavefront having a phase front at a local oscillator phase angle; mixing said electrical wavefront with said local oscillator wavefront to generate a resultant intermediate frequency wavefront; transmitting said resultant intermediate frequency wavefront to a selected delay path of a plurality of delay paths, each delay path having a delay path phase angle and providing a delay path wavefront output; and vector summing the delay path wavefront output of the selected delay path, wherein said local oscillator phase angle is approximately equal to the negative of the wavefront phase angle added to the negative of the delay path phase angle of the selected delay path.
