Abstract
Method, apparatus and systems for object tracking are disclosed. In one example, a system for tracking a plurality of objects in a venue is disclosed. The system comprises a transmitter configured for transmitting a series of probe signals in a broadcasting manner through a wireless multipath channel, wherein the wireless multipath channel is impacted by a movement of at least one of the plurality of objects in the venue; and a plurality of heterogeneous target wireless receivers each of which is associated with an object of the plurality of objects in the venue. Each of the plurality of heterogeneous target wireless receivers is configured for: receiving the series of probe signals through the wireless multipath channel between the heterogeneous target wireless receiver and the transmitter, obtaining at least one time series of channel information (TSCI) of the wireless multipath channel based on the series of probe signals received by the heterogeneous target wireless receiver, and tracking the object associated with the heterogeneous target wireless receiver based on the at least one TSCI.
