Abstract-Traditional optimization methods are not well suitable for thinning large arrays to obtain a low sidelobe level (SLL). The chaotic binary particle swarm optimization (CBPSO) algorithm is presented as a useful alternative for the synthesis of thinned arrays. The proposed algorithm can be improved by nonlinear inertia weight with chaotic mutation to increase the diversity of particles. Two examples have been presented and solved. Simulation results are proposed to compare with published results to verify the effectiveness of the proposed method for both linear and planar arrays.

Abstract. Two-dimensional unitary matrix pencil (2-D UMP) method is utilized for the synthesis of sparse planar arrays in this paper. By virtue of the equivalent matrix pencil obtained with a unitary transformation, 2-D positions including horizontal and vertical coordinates are directly found as the generalized eigenvalues of the real matrix pencils without solving poles. Owing to the utilization of a unitary transformation, the computational complexity can be significantly reduced since only the real computations are involved in the singular value decomposition (SVD) and eigenvalue decomposition (EVD) procedures. A representative numerical experiment is provided to assess the effectiveness and advantages of the proposed method.

“…Thinning arrays is formed by removing some elements from uniform arrays, and the element spacing is integral times of original uniform arrays. The elements of sparse arrays are randomly distributed on the array surface, and the element spacing is indivisible [1,4]. By contrast, sparse arrays have more freedom than thinning arrays.…”

“…Sparse arrays are facing nonlinear and complicate problems, and traditional numerical computation methods can not get the desirable solution. So more and more artificial intelligence methods are introduced in the field, such as dynamic programming algorithm [9], simulated annealing algorithm [2,[6][7][8]10], particle swarm algorithm [5], genetic algorithm [1,3,4,11], etc. Compared with linear and planar arrays, conformal cylindrical arrays have curved structure and are conformal to the carrier, so the synthesis problem of this type of antenna array is multidimensional and nonlinear problem, which is more difficult than the synthesis of linear and planar array [5].…”

Abstract-In this paper, simulated annealing algorithm (SA) is applied to the synthesis of cylindrical conformal arrays in order to suppress the peaks of side lobes by acting on the elements' positions. There are multiple optimization constraints including the number of elements, aperture and minimum element spacing. A constraint matrix is designed to make the solution meet the restriction on the minima distance between elements, and the individual matrix which forms on the basis of constraint matrix is used to express array configurations. The SA does not act on the elements' positions directly but on the variables in a smaller solution space, this indirect description method makes the SA more computationally efficient. The simulation results confirm the great efficiency and robustness of the proposed method.
