Swarm intelligence denotes a class of new stochastic algorithms inspired by the collective social behavior of natural entities (e.g., birds, ants, etc.). Such approaches have been proven to be quite effective in several applicative fields, ranging from intelligent routing to image processing. In the last years, they have also been successfully applied in electromagnetics, especially for antenna synthesis, component design, and microwave imaging. In this paper, the application of swarm optimization methods to microwave imaging is discussed, and some recent imaging approaches based on such methods are critically reviewed.

“…Although very effective global optimizers are available (e.g., Genetic Algorithms (GAs) [34][35][36], Particle Swarm Optimizer (P SO) [37][38][39][40], Differential Evolution (DE) [41,42], Memetic Algorithms (M A) [43,44], a deterministic approach is used to focus on the "effect" of data on the reconstructions thus avoiding the randomness of stochastic method. The multi-step procedure terminates at s = S opt when the stability conditions, defined in [31] for the T M case, hold true.…”

Abstract-In this paper, the solution of two-dimensional inverse scattering problems is addressed by probing the unknown scenarios with T E and T M waves. To better exploit the information content of the scattered data the multi-zooming approach is used. The results of experiments with single as well as multiple scatterers are reported and discussed also in comparison with single-polarization inversions.

“…The electromagnetic model of the OUT and the cost function optimization techniques are then the key points of model-based profile reconstruction. For example, the OUT can be parametrized using splines [3,4] or Fourier series, and the scattered field can be calculated using a Method-of-Moments to solve the 2D integral equations [5]. Thus, the number of unknowns are just the coefficients, , of the parametrized OUT profile.…”

Abstract-This contribution describes an improved technique for model-based profile reconstruction of PEC objects. The technique takes advantage of the fact that the illuminated part of the OUT is, in general, accurately reconstructed when considering independent incident angles. The knowledge of the illuminated part is used to weight the reconstructed profile for each incidence. A comparison with the extended methodology that takes into account all the incident angles simultaneously is presented, proving that the proposed technique provides faster convergence to an accurate recovery of the OUT. Application examples considering 1 and 2 OUTs are presented.
