An overlapping Sub-Aperture Method for Unified Near-Field and Far-Field Localization

The topic of positioning is challenging and complex. Many closed-form positioning solutions have been suggested, utilizing modified polar representation (MPR) to account for measurement error and sensor position errors. High sensor position errors can significantly reduce the accuracy of target location. In this paper, a novel overlapping sub-aperture (OSA) localization method is designed to mitigate inaccuracies in target positioning resulting from measurement errors and sensor position errors by a novel correlation method of these sub-apertures. The proposed method has shown superior localization accuracy in simulation results compared to existing methods.
