Abstract :
In this paper, a technique for detecting the locations of one or more persons, as well as their breath patterns, using an ultra-wideband radar sensor network, is proposed. Technical problems that occur in the estimation process, such as false detection due to indirect reflection and ambiguity problem, are introduced. Maximum-likelihood estimation is suggested as the solution to these problems and tested on 10 sets of radar measurements.
