A new approach for target location of through the wall radar imaging in the presence of wall ambiguities.

A technique for target locations in the through-the-wall radar imaging application is presented. The algorithms corrects for the shifts in target positions due to ambiguities in the wall thickness and dielectric constant. Imagining is obtained using wideband beamforming with the antennas placed against the wall. the imagining is performed for different assumed sets of wall parameters, and using two different structures of transmit and receive arrays. For each structure, a trajectory of the shifts in the target locations is formed. The target position is estimated as the intersection of the two corresponding trajectories. The paper shows the close proximity of the target estimated and true poisitions. The performance of the proposed technique is robust to the target location behind the wall and to various array structures.
