Micro-Doppler radars have been widely used for the
remote vital signs acquisition. In those cases, the signals quality is
directly related with the received power provided by the reflecting
chest-wall. In order to determine which is the optimal radar
configuration, it is important to study the signal behavior in the
near-field region considering the Radar Cross Section (RCS) of
the human chest. In this work, simulations are performed to
characterize the received signal power variation, considering the
subject distance in relation to the radar.
