Comparison of UWB technologies for human being detection with radar

Abstract

UWB radar for detection and positioning of human beings in complex environment can be developed based on different technologies such as video impulse, quasi-random noise, stepped-frequency continuous wave and frequency-modulated continuous wave. These technologies are compared on the basis of meeting functional requirements to such a radar. Relative advantages and disadvantages of these technologies for such an application as human being detection and positioning are pointed out. Recommendations for selection of an optimal technology are given.
