A method for processing radio frequency reflections is provided. The
method applies an RF waveform to a transmission line that is a conductor
used for providing a utility service. The method uses a RF waveform
generator to transmit UltraWideband (UWB) RF waveforms through the
conductors of a building. The RF waveforms are emitted at emission points
that can be impedance discontinuities along the transmission line or
impulse radios. The emitted RF waveforms reflect off of objects in the
building and are received at reception points that can be impedance
discontinuities or impulse radios. These reflections are processed to
determine movement of objects within or near the building. Based on the
reflections of the RF waveforms, the position of the objects within or
near the building can be determined.
