Abstract
Systems, device and methods are provided for calibrating an antenna array comprising a plurality of antennas such as a plurality of transmit and receive antennas by utilizing an arena comprising one or more targets and a medium. The methods may comprise transmitting a plurality of Radio Frequency (RF) signals from at least one RF antenna of a plurality of RF antennas towards an arena, obtaining by the antenna array affected multiple RF signals from the arena, measuring the plurality of reflected RF signals by a Radio Frequency Signal Measurement Unit (RFSMU) and calculating a plurality of channel responses from said plurality of affected RF signals, providing by at least one processing unit a first model, which is configured to produce an expected electromagnetic (EM) channel responses of the antenna array and the arena and providing a second model, which comprises a relation between the first model and the antenna array calibration parameters and calculating the array calibration parameters to calibrate the antenna array.
