The design of sparse arrays able to radiate focused beam patterns satisfying a given upper-bound power mask with the minimum number of sources is a research area of increasing interest. The relatedExpand
Deterministic Synthesis of Uniform Amplitude Sparse Arrays via New Density Taper Techniques
Uniform amplitude sparse arrays have recently gained a renewed interest and a number of synthesis techniques, mainly based on global optimization algorithms, have been presented. In this paper, afterExpand
An Effective Hybrid Approach for the Optimal Synthesis of Monopulse Antennas
The problem of synthesizing "optimal" sum and difference patterns subject to arbitrary sidelobe bounds by means of a simple feeding network is dealt with. It is shown how a hybrid optimizationExpand
Solving Some Array Synthesis Problems by Means of an Effective Hybrid Approach
Most global optimization based synthesis procedures act in essentially the same way on all the involved variables. In this paper, it is theoretically discussed and numerically emphasized how explicitExpand
A hybrid approach for the optimal synthesis of pencil beams through array antennas
A hybrid approach to the synthesis of excitations and locations of nonuniformly spaced arrays in order to achieve optimal focusing in any given direction is proposed and discussed. The approach takesExpand
Optimal synthesis of difference patterns subject to arbitrary sidelobe bounds by using arbitrary array antennas
Two new approaches to the optimal synthesis of difference patterns are proposed that can deal in an effective fashion with arbitrary sidelobe bounds. The first approach, which amounts to solving aExpand
Improving the Performances of the Contrast Source Extended Born Inversion Method by Subspace Techniques
In this letter, it is shown that the performances of the CSEB method can be improved using the stable portion of the induced currents in two ways, i.e., by computing a good initial guess of the contrast function. Expand
On the Solution of 2-D Inverse Scattering Problems via Source-Type Integral Equations
In this paper, effective and accurate tools and procedures for the solution of forward and inverse scattering problems have been proposed and discussed. Expand
Maximally Sparse, Steerable, and Nonsuperdirective Array Antennas via Convex Optimizations
A new method for the synthesis of planar, nonsuperdirective, maximally sparse, and steerable arrays is proposed and tested on several benchmarks. Expand
Inverse scattering from phaseless measurements of the total field on a closed curve.
A new approach for quantitative electromagnetic imaging of scatterers located in free space from phaseless data is proposed and discussed. The procedure splits the problem into two steps. In theExpand
