Adaptive interference cancellation

In this paper is describe an adaptive digital beamforming monopulse radar system that used a uniform linear phased array in receive mode. A digital beamforming consists antenna elements (array), receiver modules and analog-to-digital converters, and controller. These adaptive radar systems have been successfully applied to the practical tasks of processing measured data from the experimental phased-array antennas. These antennas follow the classic "digital beamforming" model since we have available the digitized amplitude and phase of the received signal at every antenna element. In receive mode the main advantages of adaptive radar systems are improve fast adaptive pattern nulling, antenna self-calibration, ultra-low sidelobes, adaptive space-time processing.
