Ris-Aided mmWave MIMO Radar System for Adaptive Multi-Target Localization

Paper i proceeding, 2021

In this paper, we propose to utilize a reconfigurable intelligent surface (RIS) aided millimeter wave (mmWave) multiple-input-multiple-output (MIMO) radar system for multi-target localization. The goal is to detect multiple targets with sufficient accuracy using an adaptive localization algorithm utilizing the concept of hierarchical codebook design. The simulation results show that in case of a blocked line of sight (LOS) between the transmitter and the targets, the receiver can still localize all the targets with very good accuracy using the RIS.
