Characteristies of 2D-FDA Radar

The conception of frequency diverse array ( FDA) is extended in this paper, center frequency modulated pulses are settled in its array witch is defined 2D-FDA radar in this paper. The beamforming as well as direction pattern changing with range and time are analyzed in 2D-FDA radar. For its application in airborne detection radar, the clutter characteristics and its distribution are studied by simulation. The scheme for moving target detection in clutter environment is proposed at last, explaining how the target SCNR can be promoted. The 2D-FDA will be a novel idea for airborne radar detecting targets in clutter environment.
