Reducing Bias for Closed‐Form TDOA Localization in Unified Near‐Field and Far‐Field Model

IET Signal Processing, Volume 2026, Issue 1, 2026.
Bias is a fundamental metric for evaluating the average error of an estimator, where lower bias indicates an estimator closer to the true value. Recent studies on time difference of arrival (TDOA) localization have introduced the modified polar representation (MPR) to unify near‐field and far‐field scenarios, enhancing robustness to the source range ...
