<p style='text-indent:20px;'>This paper is concerned with the inverse problem of time-harmonic acoustic scattering by an unbounded, locally rough interface which assumed to be a local perturbation plane. The purpose this recover from near-field measurement given on straight line segment finite distance above and generated point sources. Precisely, we propose novel version linear sampling ...

Linear systematic sampling design is very simple and operationally convenient in practice, but, when the population size is not a multiple of the sample size, results in a variable sample size and in this case sample mean as an estimator of the population mean is not unbiased. To overcome these difficulties and in some cases to increase the efficiency, a number of modifications of linear system...

This study describes a hybrid technique for identification of buried objects. The object’s shape and electromagnetic profile are reconstructed from evaluations of electrical permittivity and conductivity. The method suggests a combination of linear sampling and optimization. Linear sampling method (LSM) is used to recover shape and metaheuristic optimizations essential to reconstruct the inside...
