In this paper we give an overview on autonomous navigation, object detection and imaging by UWB sensor networks. We describe coherent and non-coherent approaches of data fusion for imaging and object localization that rely on different levels of synchronous multistatic and asynchronous sensor cooperation. Detection and identification of time variant object(More)
Efficient detection of people hidden by walls or rubble is of interest for rescue, surveillance and security operations. A useful method applies an ultra-wideband radar approach for this purpose since electromagnetic waves in the lower GHzrange penetrate most non-metallic materials. The paper gives a short overview of the particular radar conception and(More)
Ground-penetrating radar (GPR) is capable to detect plastic antipersonnel landmines as well as other subsurface targets. In order to reduce false alarms, an option of automatic landmine discrimination from neutral minelike targets would be very useful. This paper presents a possibility for such discrimination and analyzes it experimentally. The authors(More)
Real-time MIMO (Multiple Input to Multiple Output) channel sounding is already a well established technology for experimental propagation studies in mobile radio which finally delivers the CIR matrix (CIR: channel impulse response), [1]. However, the bandwidth of the existing real-time MIMO sounder systems is somewhat limited to 100...240 MHz. This is by(More)
6 The project ultraMEDIS addresses the specific advantages of ultra-wideband (UWB) radio 7 sensors for medical applications: high temporal and spatial resolution, good tissue 8 penetration, low exposition by radio waves, and compatibility with existing diagnostic and 9 therapeutic equipment even for simultaneous applications. The proposed UWB sensors 10(More)
