Abstract
Imaging techniques based on time reversal method are particularly suitable for detection of targets embedded in a strongly scattering media. Generally in time reversal imaging technique we need to know the Green's function of the medium and the exact locations of the transmitter and receiver antennas. We introduce a target imaging method in which imaging is made with an arbitrary placement of the transmitting or receiving antennas. Numerical simulations are used to illustrate the capabilities of the proposed algorithms in different scenarios. We use the two-dimensional finite difference time domain method in our simulations. The numerical simulations are done for a typical through-the-wall scenario. We also present results in which the same method is used for tracking targets behind the wall.
