  In this paper, we consider a hybrid Analog and Digital (A/D) receiver
architecture with an extremely large Dynamic Metasurface Antenna (DMA) and an
$1$-bit resolution Analog-to-Digital Converter (ADC) at each of its reception
radio-frequency chains, and present a localization approach for User Equipment
(UE) lying in its near-field regime. The proposed algorithm scans the UE area
of interest to identify the DMA-based analog combining configuration resulting
to the peak in a received pseudo-spectrum, yielding the UE position estimation
in three dimensions. Our simulation results demonstrate the validity of the
proposed scheme, especially for increasing DMA sizes, and showcase the
interplay among various system parameters.
