Abstract
The present disclosure relates to detecting presence using a low-cost radar. A transmitted signal including repetitions of a transmitted signal is emitted from a transmitting antenna. A received signal including a combination of a plurality of reflections of the transmitted signal is received at receiving antennas. For each received signal, the received signal is processed to determine whether a threshold has been exceeded. When the received signal exceeds the threshold, presence due to a motion from a moving body is determined. When the received signal does not exceed the threshold, a periodicity of the received signal is measured to determine whether the periodicity of the received signal is within a vital range, and presence due to a vital sign is determined when the periodicity is within the vital range.
