Resumo(s)
The bio-radar system can measure vital signals accurately, such as the respiratory signal, by using the Doppler effect principle that relates the received signal properties with the distance change between the radar antennas and the person's chest-wall. In this paper, the antenna radiation pattern influence on the quality of the received signal is analysed. Moreover, we show that the antenna with a narrow beam leads to a better signal to noise ratio.
