A new approach for target localization of through-the-wall radar with unknown walls

Based on imaging through assumed wall parameters, an approach of target localization for through-the-wall radar in the presence of wall ambiguities is proposed. The target location is estimated by finding the maximum pixel point in composite image which is composed by image sequences corresponding to different assumed wall parameters. The proposed approach is available for target localization with unknown wall parameters and robust to the target location behind the wall.
