Claim Text:
1. A method for receiving and/or transmitting waveforms by two or more phased arrays, the method comprising: i. applying a first coherent processing to two or more signal sets comprising signal portions being received or transmitted by corresponding two or more phased arrays (PAs) operating in respective receiving or transmitting modes, wherein said first coherent processing comprises converting the sets of signal portions being received into corresponding sets of directional signals or converting sets of directional signals into the sets of signal portions to be transmitted, said converting comprising coherent integrations of each set in one of the sets of signals portions or the sets of directional signals for obtaining the other one of said sets of signals portions and said sets of directional signals; each of the directional signals being indicative of the angular frequencies, amplitudes and phases of waveforms to be received or transmitted; and ii. applying a second coherent processing to a coherent set of directional signals or to said two or more sets of the directional signals to perform the respective transmitting and receiving modes, wherein said second coherent processing of the transmitting and receiving modes comprises adjusting phases of respectively said coherent set of directional signals and said sets of the directional signals, the phase being adjusted in accordance with spatial dispositions between the PAs and the angular frequencies of the directional signals, the phase adjusting in the transmitting and receiving modes providing respectively the sets of the directional signals and the coherent set of directional signals, thereby enabling to utilize said two or more PAs to carry out at least one of coherently receiving and coherently transmitting with improved gain of one or more waveforms propagating in one or more directions.
