Interference resistant method for in-situ operational calibration and compensation of gain and phase variations in antenna array receiver RF and analog front-end electronics

A receiver comprising:

• a plurality of antenna paths with respective antennas and respective electronic components:
• a calibration source configured to apply at least one calibration signal to at least one of the plurality of antenna paths at a location prior to at least one respective electronic component of the at least one of the plurality of antenna paths and after at least one respective antenna of the at least one of the plurality of antenna paths;
• and
• a processor configured to:
• combine data streams from an interference subset of respective antenna paths generated using sampling signals with at least one data stream from a calibration subset of the respective antenna paths generated using the at least one calibration signal applied to the calibration subset of the respective antenna paths to generate interference-cancelled calibration waveforms;
• and
• generate calibration weights based on the interference-cancelled calibration waveforms;
• and
• combine further data streams from the calibration subset of the respective antenna paths with the calibration weights to reduce variations introduced by at least one re v electronic component provided in the at least one of the respective antenna paths, wherein the variations comprise phase variations, amplitude variations, or a combination thereof.
