Employment of ground-based positioning systems has been consistently growing over the
past decades due to the growing number of applications that require location information …

This paper investigates the constrained weighted least squares (CWLS) source localization
problem by using time difference of arrival and frequency difference of arrival …

Time difference of arrival (TDoA) based on a group of sensor nodes with known locations
has been widely used to locate targets. Two-step weighted least squares (TSWLS) …

Considering the estimation accuracy reduction of Frequency Difference of Arrival (FDOA)
caused by relative Doppler companding, a joint Time Difference of Arrival (TDOA), FDOA …

The maximum likelihood estimator (MLE) and its performance for the localization of a
stationary emitter using a network of spatially separated passive stationary sensors is …

Multi-station joint localization has important practical significance. In this paper, phase
difference of arrival (PDOA) information is introduced into the joint time difference of arrival …

The cross ambiguity function (CAF) has been commonly used to find time difference of
arrival (TDOA) and frequency difference of arrival (FDOA). In most cases, direct computation …

For the joint time difference of arrival (TDOA) and angle of arrival (AOA) location scene, two
methods are proposed based on the rectangular coordinates and the polar coordinates …

In this paper, we address the problem of direct position determination (DPD) for moving
sources. Different from traditional two-step localization methods where the intermediate time …

We consider identifying the source position directly from the received source signals. This
direct position determination (DPD) approach has been shown to be superior in terms of …
