Abstract
A method of detecting human presence includes using a radar sensor to monitor a space, and receiving an output signal from the radar sensor. A Fourier transform is performed on the output signal to produce a signal spectrum. It is decided whether the output signal is indicative of human activity dependent upon at least one acoustic feature of the signal spectrum and at least one spectral feature of the signal spectrum.
