Abstract
Systems and methods for utilizing two or more phased arrays to coherently receive and/or transmit waveforms to one or more directions. The method includes applying a first and a second coherent processing to two or more sets of signal portions received or transmitted by corresponding two or more phased arrays. In reception mode, the first coherent processing includes converting the sets of signal portions received into corresponding sets of directional signals, by applying coherent integrations to each set signals portions such that each of the resulting directional signals being indicative of the angular frequencies, amplitudes and phases of the received waveforms. In reception mode, the second coherent processing includes adjusting phases of respectively the sets of the directional signals according to spatial dispositions between their respective phased arrays and the angular frequencies of the directional signals, thereby generating a coherent set of directional signals.
