Paper Abstract

One of the challenges of using synthetic aperture radar (SAR) to detect and classify an object behind a wall consists of determining the amount of signal attenuation introduced by the signal's propagation through the wall. This attenuation is difficult to determine because the electromagnetic properties of the wall, along with its thickness are normally not known a priori. We describe a procedure for determining the necessary parameters given that the SAR has high enough resolution such that the front and the rear surfaces of a uniform wall or cinder block wall can be determined from the SAR image. In addition, we provide a procedure for estimating the signal level behind the wall, or equivalently the attenuation due to the wall, from measured returns from its front and rear surfaces. We demonstrate the effectiveness of this procedure using data generated by XPATCH simulations.
