Abstract
Methods, apparatus and systems for wireless human-nonhuman motion detection are described. For example, a described method comprises: transmitting a wireless signal through a wireless multipath channel of a venue; receiving the wireless signal through the wireless multipath channel, wherein the received wireless signal differs from the transmitted wireless signal due to the wireless multipath channel that is impacted by a motion of an object in the venue; obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the received wireless signal; computing an autocorrelation function (ACF) based on the TSCI; computing at least one ACF feature of the ACF or a function of the ACF; computing an ACF statistics, a motion statistics, a speed statistics, and a gait statistics based on the at least one ACF feature of the ACF or the function of the ACF; and in response to a determination that the motion is detected, classifying the object associated with the detected motion as a human or a non-human, based on: the ACF statistics, the motion statistics, the speed statistics, and the gait statistics.
