Abstract

Two beam broadening techniques for active electronically scanned array (AESA) antennas using phase-only control are proposed. As a preliminary step, the problem dimensionality is reduced from five to only two variables. The first method is suitable for various applications and involves an efficient optimization of phase tapering. The second technique is more specific for radar AESAs typically transmitting pulse trains used for coherent integration. Here, time dependent phase modulation is employed to effectively produce amplitude tapering resulting in beam broadening.
