Compact UWB Indoor and Through-Wall Radar with Precise Ranging and Tracking
Artikel i vetenskaplig tidskrift, 2012
Ultrawideband (UWB) technology has many advantages compared to its narrowband
counterpart in many applications. We present a new compact low-cost UWB radar for
indoor and through-wall scenario. The focus of the paper is on the development of the signal
processing algorithms for ranging and tracking, taking into account the particular properties
of the UWB CMOS transceiver and the radiation characteristics of the antennas. Theoretical
analysis for the algorithms and their evaluations by measurements are presented in the paper.
The ranging resolution of this UWB radar has achieved 1-2 mm RMS accuracy for a moving
target in indoor environment over a short range, and Kalman tracking algorithm functions
well for the through-wall detection.
