This work explores the utilization of arrays to enhance ultrawideband (UWB) performance in non-line-of-sight (NLOS) environments and to provide range extension through operation in low signal-to-noise ratio (SNR) environments. Processing algorithms are described and evaluated using measured data sets provided by UltRaLab. Array processing is used to excise inconsistent detections and to provide estimates of measurement reliability for use in localization solvers. Angle-of-arrival (AOA)-based metrics are considered for time-of-arrival (TOA) systems, and TOA-based metrics are investigated for time difference-of-arrival (TDOA) systems. General trends suggest that the integration of array processing can significantly enhance performance in non-LOS, low SNR environments.
