Signal Processing Steps for Objects Imaging Through the Wall with UWB Radar
نویسنده
چکیده
UWB radar system facilitates us to estimate positions and shapes of the objects behind the wall. It has a great utilization especially for rescue and security applications. This paper briefly describes all signal processing steps that are required for Imaging of the objects scanned by ultra wideband radar device. It involves the description of the basic scanning method, data preprocessing and calibration, migration methods, wall parameters measurement techniques and compensation of the wall effect on wave that penetrate through the wall. The practical results from real measurements with M-sequence UWB radar device are shown. Keywords—UWB radar system, through the wall imaging, SAR scanning, signal processing.

UWB Impulse Radar for Through-The-Wall Imaging
Ultra-Wideband (UWB) is the promising technology for localization of the objects behind the walls. Recent terrorist activities and law-enforcement situations underscore the need for effective through-wall detection. UWB radar signals has extremely large frequency spectrum and since low frequencies has more penetration capabilities through dielectric materials it is best suitable for Through-the...
