Ranging, ositioning, and counting of multiple targets using IR-UWB radar systems

In recent years, the impulse radio — ultra wideband (IR-UWB) radar system has received a large amount of attention due to its wide variety of practical applications, such as distance measurement and counting of moving objects, intruder detections, electronic fences, location finding of victims at disaster sites, inspection of internal materials by penetration, through-wall surveillance, heart-beat and respiration monitoring of patients, snow depth measurement, and so on. A building energy management system (BEMS) is also one of the good applications of the IR-UWB radar system, where the radar system consistently measures the number of people and their locations in every room and floor of the building without invoking privacy issues, so that the building can autonomously save unnecessary energy consumption.
