Array Zooming Optimization for Near-Field Localization With Movable Antennas

Boyu Teng, Rui Wang, Xiaojun Yuan, Yuxin Duan

Claims

C1strongest claim

the proposed AZ strategy adaptively optimizes array configurations under varying signal-to-noise ratios (SNRs), substantially outperforming both conventional fixed-spacing arrays and Cramer-Rao bound (CRB)-based AZ benchmarks in localization accuracy.

C2weakest assumption

That fusing multiple measurements from different array spacings can reliably eliminate spatial aliasing without introducing new errors from movement or calibration, and that the derived false-peak distribution accurately models practical multi-modal likelihoods.

C3one line summary

The paper introduces an array zooming optimization using movable antennas that fuses multi-measurement observations to suppress false peaks and achieve better near-field localization accuracy than fixed arrays or CRB-based methods.
