Localization has gained increased attention due to the availability of powerful processing systems and grown
demands on software. Meanwhile, there are many software applications benefiting from the Global Positioning System for outdoor scenarios, but lacking indoor support, since systems for indoor positioning are either inaccurate or too costly. Being aware of this problem, the IEEE 802.15.4a standard was compiled, incorporating explicit support for Ultra-Wideband positioning with the first chips being available now. The paper presents the steps taken to design the hardware for an Ultra-Wideband radar using off-the-shelf components.
