Closed-Form Method for Unified Far-Field and Near-Field Localization Based on TDOA and FDOA Measurements

open access: yesRemote Sensing
When the near-field and far-field information of a target is uncertain, it is necessary to choose a suitable localization method. The modified polar representation (MPR) method integrates the two scenarios and achieves a unified localization with ...
