Metaprism-aided NLOS Target Localization

In future wireless systems, radar and communication functionalities are expected to be integrated to improve the awareness of the network and enable new applications. To make the radar work even in the presence of obstacles, this paper proposes the use of a passive frequency-selective metasurface, named metaprism, to allow a conventional frequency-modulated continuous wave (FMCW) radar to estimate both the range and the angle of a target hidden by an obstacle. Results indicate that it is possible to obtain a very accurate angle and range estimate without involving additional active devices and/or multiple antennas at the radar.
