However, a number of factors significantly reduce human exposure to RF generated by radar systems, often by a factor of at least 100: Radar systems send electromagnetic waves in pulses and not continuously. WebAs predicted by the Fourier theory, the maximum unambiguous Doppler shift a pulse radar system can detect is half of its PRF. This also translates to the maximum unambiguous speed a radar system can detect. In addition, the number of pulses determines the resolution in the Doppler spectrum, which determines the resolution of the speed … hanson oh holy night
