Through wall ranging and imaging using UWB random noise waveform: System design considerations and preliminary experimental results

In this work, a portable and real-time through-wall random noise radar is presented. The system is inherently covert and is immune from interference and jamming since a random noise waveform is used. By combining mature cross-correlation and SAR algorithm with FPGA-based receiver technology, the system is able to perform real-time range detection as well as imaging of targets, including human beings, behind a wall.
