Abstract

The frequency diversity array (FDA) is capable of producing a range-angle dependent "S" beampattern, unlike conventional phased arrays that only provide directional beams in the angular domain, but it can only scan in a fixed direction, while frequency diversity arc array (FDAA) has a beam scan-ning capability within a 360 degrees range, which can realize all-round monitoring of the target position and provide a more flexible method for radar communication. In this letter, a dot-shaped beampattern optimization method for FDAA is proposed, which uses amplitude weighting and symmetric non-uniform frequency offset to achieve flexible beam scanning
