Abstract — For the problem of the broadband pattern synthesis for arbitrary arrays, the pattern synthesis method based on the convex optimization and its solving software are proposed. Therein, for the particularity of the broadband lowest sidelobe level pattern synthesis, and combining the excellent numerical solving methods for convex optimization, and the nearest convex optimization solving software cvx, the broadband lowest sidelobe level pattern synthesis algorithm for arbitrary array is modeled and solved, and the specified broadband synthesis pattern is obtained. At last, the correctness and effectiveness is attested by the particular simulations, and it is indicated that the proposed algorithm is better than other iteration algorithms.
