Feasibility of TDOA localization with a single moving receiver and stationary source
Every paper/article I've read on the subject of TDOA localization is concerned with some combination of 2+ stationary receivers (or, sometimes, 1 stationary + 1 moving). There are also some papers ...

Subsample Time Delay Estimation
Often we need to estimate the time difference of arrival between two signals to find the location of a target. Many algorithms gives the time delay corresponding to a sample number or time delay is a ...
