Estimation of Wall Parameters From Time-Delay-Only Through-Wall Radar Measurements
Original language description
Knowledge of the basic characteristics of the wall is important for the proper function of through-wall radars (TWR). In this paper, we introduce an estimation method that can provide the unknown wall parameters in real time. Our algorithm is based on amodified version of common midpoint processing, a technique adopted from geophysics. Using this method, it is possible to estimate both the thickness and the permittivity of the wall from time-delay-only measurements performed at several different transceiver-receiver separations. Time-delay estimation of echoes backscattered from the wall at each antenna separation is performed by a subspace super-resolution method. The performance of our estimation algorithm is verified by simulations, and we also present the results for two real brick walls measured using the time-domain technique. The estimated wall parameters can be utilized for improving the accuracy of real-time locating and tracking of moving humans by TWR.
