Abstract
Methods, apparatus and systems for outdoor target tracking are described. In one example, a described system comprises: a transmitter, a receiver, and a processor. The transmitter is configured for transmitting a first wireless signal through a wireless multipath channel. The receiver is configured for receiving a second wireless signal through the wireless multipath channel. One of the transmitter and the receiver is a located device at a known location. The other of the transmitter and the receiver is a moving device. The second wireless signal differs from the first wireless signal due to the wireless multipath channel which is impacted by a movement of the moving device. The processor is configured for: obtaining a plurality of time series of channel information of the wireless multipath channel based on the second wireless signal, computing a spatial-temporal information (STI), and tracking the moving device based on the STI.
