Abstract
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.
