Remote human presence detection system

Methods for remote detection of humans can include the step of transmitting vertically polarized electromagnetic signals into an area of interest (AOI) when no humans are present. A first time domain measurement of return response signal energy from the AOI can be accomplished to establish a background signal. A second time domain measurement of response signal energy from the AOI can be made when at least one human is present, to establish a background-plus-human signal. The two signals can be subtracted to yield a reference time domain human signal. The electromagnetic signal is periodically re-transmitted. The background subtracted from subsequent response energy, and the result compared to the reference time domain human signal. A visual or audible indication occurs when the resulting signal matches the reference signal. Fast Fourier Transforms (FFT) of the time domain signals can be used to yield frequency responses, which can be monitored.
