Abstract: This paper investigates the resolution and robustness of the multiple signal classification (MUSIC) method to locate small three-dimensional (3D) anisotropic scatterers near the medium interface in a multilayered background. An enhanced MUSIC algorithm developed for free-space background is extended to solve such a problem. Because its indicator is built in a stable signal subspace, which is continuous across the medium interface, better stability and higher resolution against noise are observed for the proposed method compared to the known standard MUSIC method. Numerical simulations with various medium interfaces and noise levels are conducted to verify the performance of the introduced MUSIC method. © 2012 Optical Society of America.
