Abstract

Communication systems are not dedicated to sensing tasks. Before really using them insensing, there are a number of difficulties that should be addressed. Distance, AoA, andDoppler frequency are usually jointly used in traditional ways of target tracking. In ISACsystems, the distance measurement is limited by communication bandwidth, the AoA accuracyis limited by antenna aperture. In this talk, I shall show that the Doppler frequencies ofcommunication signals might be sufficient to track a moving target, as long as there areadequate directions of observation. Note that it is much easier to obtain an accurate estimation of Doppler frequency than the other two. The justification is conducted in Wi-Fi, LTE and mmWave bands respectively for the tracking of walking person, robot and drone.
