Interpretation of MUSIC for Location Detecting of Small Inhomogeneities Surrounded by Random Scatterers

الملخص EN

We consider the MUltiple SIgnal Classification (MUSIC) algorithm for identifying the locations of small electromagnetic inhomogeneities surrounded by random scatterers.

For this purpose, we rigorously analyze the structure of MUSIC-type imaging function by establishing a relationship with zero-order Bessel function of the first kind.

This relationship shows certain properties of the MUSIC algorithm, explains some unexplained phenomena, and provides a method for improvements.
