Abstract:

Different phased-array only providing angle-dependent array factor, frequency diverse array (FDA) offers both angle-and range-dependent array factor. In this letter, we optimally design FDA frequency offsets by formulating a constrained nonlinear programming problem to produce range-angle focusing beampattern. The corresponding time-variance characteristics of the optimized FDA beampattern are also analyzed. The proposed method is verified by simulation results, which superiority to existing Log-FDA, Hamming-FDA and GA-FDA methods are validated.
