Development and Implementation of Ultra-Wideband See-Through-Wall Imaging System Based on Sampling Oscilloscope

A low-cost experimental UWB synthetic aperture radar has been developed for high-resolution see-through-drywall imaging application. The developed SAR-based system is comprised of an UWB Vivaldi array, off-the-shelf components, and RF instruments. System integration including hardware and software aspects is in detailed discussion. The running system focuses on 8-12 GHz operation, but the very flexible system architecture allows it to be easily scaled to cover the lower frequency band, such as 2-4 GHz which is more suitable for the see-through-concrete wall application.
