Choi, J. W., Yim, D. H., & Cho, S. H. (2017). People counting based on an IR-UWB radar sensor. IEEE Sensors Journal , 17 (17), 5717-5727. https://ieeexplore.ieee.org/abstract/document/7968432 In this article, Choi , Yim and Cho (2017) focus on the application of the people counting sensor using an impulse radio ultra-wideband radar sensor. As of now, lots of people counting sensor has been research but most of them are using image based. Image based people counting sensor has a disadvantage in terms of privacy. But by using people counting sensor using an impulse radio ultra-wideband (IR-UWB) radar sensor, privacy is not a concern as image of occupants is not used. “This enables people counting even in places where privacy is important, such as hotels or private property” The IR-UWB is a technique that uses an impulse signal with a very short duration in the time domain, which occupies a wideband in the frequency domain. The IR-UWB radar gives out impulse signal to detect p
