Electromagnetic inverse scattering (EMIS) is a noninvasive examination tool, which holds the promising potential in science, engineering, and military applications. In contrast to conventional tomography techniques, the inverse scattering is a quantitative superresolution imaging method since it is capable of accommodating more realistic interactions between the wavefield and the probed scene. In...
The nonlinear least-square method is presented for the synthesis of the reconfigurable arrays by only modifying the excitation phases. The proposed method is aimed at synthesizing two pattern beams or three pattern beams by means of the phase-only control strategy. This method is able to determine the common excitation amplitudes and the various sets of excitation phases at the same time. Several...
This paper proposes a modified real genetic algorithm (MGA) for the synthesis of sparse linear arrays and presents the basic steps of the MGA in detail. The designing requirements of the shaped-beam patterns are satisfied by using the MGA to optimize the position and excitation of the elements under the given precondition of the number of elements, aperture and minimum element spacing. The finally...
