Millimeter-wave massive arrays for indoor SLAM

The adoption of millimeter waves will give the possibility to integrate massive antenna arrays inside next generation tablets and smartphones, with consequent significant enhancement of their communication performance. Besides communication, the availability of such a technology can also enable other interesting applications such as personal radar for accurate simultaneous localization and mapping (SLAM). In this paper we investigate the feasibility of 3D environment mapping for SLAM applications at millimeter waves exploiting massive antenna arrays on the user's mobile device. Frequency selectivity and phase quantization effects are accounted for to characterize the achievable angle and range resolution necessary to collect environmental 3D information under transmission power and scanning time constraints.
