Optimization criteria in the design of medical UWB radars in compliance with the regulatory masks

A general method is described to select an optimal set of parameters to design a pulse radar system [1] for heart motion detection [2,3]- Relating to the tracking of heart wall movement, the required acquisition time and sampling frequency are determined and subsequently pulse repetition frequency, pulse echo averaging and pulse power are obtained under regulatory mask power limitations defined for UWB emissions [4,5]. Although essentially theoretical and sometimes quite trivial, the reported model may be used as a reference for the parameters setting in the design of UWB radars for the acquisition of the temporal motion signal of internal body organs [6,7].
