—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)

— 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 GHz-range penetrate most non-metallic materials. The paper gives a short overview of the particular radar conception and(More)
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)
UWB radar system facilitates us to estimate positions and shapes of objects behind the wall. We have made real through the wall SAR measurements with bistatic M-sequence UWB radar system. A metal plate, an aquarium filled with water and a wooden cupboard inside the room with concrete wall have been scanned. The simple and fast algorithm for compensation of(More)
Radar based detection of earthquake survivors exploits the modulation of the backscattered signal by body motions of the victim. The most challenging task is the detection of respiration activity of an unconscious person. The principle of breathing motion detection by radar is explained and the major handicaps as well as appropriate counter measures are(More)
