Researchers Submit Patent Application, 'Method for Detection of Movement of a Specific Type of Object Or Animal Based on Radar Signals', for Approval

摘要

"The invention comprises, in one form thereof, a method of detecting movement, including 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 frequency domain signal spectrum. The frequency domain signal spectrum is transformed into an acoustic domain signal. It is decided whether the output signal is indicative of movement of one of a predetermined object and a non-human animal dependent upon at least one feature of the acoustic domain signal and at least one spectral feature of the signal spectrum.
