Unlike a conventional phased array that offers directivity only in the angle domain, a frequency diverse array (FDA) is capable of producing a beampattern that is dependent on both angle and range. In this letter, a transmit beamforming method for an FDA is proposed that uses logarithmic frequency increments that have a nonuniform spacing. Compared to existing methods, the proposed architecture offers an improved range–angle localization with reduced sidelobe values. Simulations results for single and multiple target beampatterns are shown in order to assess the efficacy of the proposed architecture.
