Near-field Time-Reversal Imaging Combined with Numerical Mode Matching method

A new method of combining the multiple signal classification (MUSIC) algorithm with the Numerical Matching Method (NMM) is proposed to realize the time reversal (TR) imaging with near-field scattering of multi-object scene. The NMM is used to compute the bistatic forward scattering of multiple objects to get the UWB scattering field. Then the TR-MUSIC algorithm utilizes the NMM calculation result as the input to achieve multi-object imaging. Experiments illustrate that the algorithm has efficient performance.
