Paper Abstract

An innovative approach is introduced herein for three-dimensional (3D) imaging of objects or people hidden behind obstacles such as walls. The Xaver 800, new micro-power Ultra Wideband (UWB) radar utilizes unique signal and image processing algorithms, enabling real-time acquisition and presentation of 3D images with high resolution of objects hidden behind walls. 'Xaver 800' offers the ability to perform life-saving operations with greater success and with a smaller risk to the operatives and to those they are trying to protect. Many technical challenges are encountered when working in real-world environment. Tough link-budget, distortions, and de-focusing when passing through walls with complex construction, are only a partial list of the problems an effective through-wall-imaging system should overcome. In addition, real-time operation limits the available integration time to the operational frame rate. Efficient utilization of the available integration time can improve the systems' link budget and thereby enhance the overall performance of the system. In cases where the link-budget parameters are tough, an efficient integration method can enable a reasonable refresh rate and therefore real-time operation. An approach to compensating for different attenuation sources and signal loss through 'Non-Uniform Integration' is discusses in this paper.
