Description
Summary:A new time reversal method is proposed to infer the location of an unknown extending target in a complex environment. In our method, the wavelet analysis and scalogram of energy density are first introduced into the electromagnetic time reversal process to improve the accuracy and to eliminate noises. The computation results show that the new technique can refocus the unknown target better than using traditional time reversal.
