THROUGH-THE-WALL TARGET LOCALIZATION WITH TIME REVERSAL MUSIC METHOD

By W. Zhang, A. Hoorfar, and L. Li

Full Article PDF (311 KB)

Abstract:
Time Reversal Multiple Signal Classification (TR-MUSIC) method is studied and adapted for the detection and localization of multiple targets behind the wall in this paper. TR-MUSIC does not involve the FDTD solver for the implementation of the backpropagation of the time reversed field and is very computational efficient. The Green's function vectors for the computation of the TR-MUSIC pseudo-spectrum is efficiently evaluated with the saddle point method for a homogeneous wall. By employing the null space of the multistatic response matrix, simultaneous localization of multiple targets behind the wall can be achieved by TR-MUSIC method. Numerical results are presented to show the effectiveness of through-the-wall imaging (TWI) with TR-MUSIC method.
