Abstract
Unlike phased array adopting invariable carrier frequency, frequency diverse array (FDA) introduces a tiny frequency increment across the array elements, leading to a transmit beamforming associated with the parameters of range and angle. However, the beampattern generated by the conventional FDA is range-angle coupling, which is detrimental for target localization and interference suppression. In this paper, a new FDA scheme utilizing nonuniform element spacing and nonlinear frequency offset is proposed to provide a range-angle decoupled beampattern with narrower main lobe and no periodicity. Simulations and comparative results are presented to verify the superiority of the proposed scheme over the existing systems.
