In this paper, we focus on a 2-D target localization problem based on TDOA
measurements with inaccurate collaborative sensors in a multipath environment.

RSSI is used along with TDoA
and ToA in the work of Laaraiedh et al.
In , the CS theory was utilized to estimate time difference of arrival (TDOA
) and obtained higher estimation accuracy than the generalized cross-correlation (GCC) method.
And the maximum overshoots and time difference of arrival (TDOA
, defined as the time difference ([t.sub.PFC] - [t.sub.FL_PFC]) between the two methods for the vehicle to do the switching maneuver near the waypoint) displayed in the areas A, B, C, D, E, and F are listed in Table 2.
An application of the proposed improved UKF method to the mobile source localization problem is provided, where we consider source localization by a network of passive sensors using noisy time difference of arrival (TDOA
If location accuracy is crucial for the application, other techniques such as Time Difference Of Arrival (TDOA
) with multiple synchronized MSs could be used to improve the location accuracy [4, 15, 16].

measurements," IEEE Transactions on Signal Processing, vol.
The other model-based techniques are time of arrival (ToA) , time difference of arrival (TDoA
) , and angle of arrival (AoA) .
In the range-based positioning there are several different methods to obtain a distance between nodes in RF networks: techniques that translate the radio signal strength into distance (RSS), time of flight (TOF), time of arrival (TOA) or differenced time of arrival (TDOA
) described in (Chen et al., 2012; Lourenco et al., 2013) or angle of arrival (AOA) (Peng and Sichitiu, 2006).
Time delay or Time Difference of Arrival (TDOA
) permits inferring the position of a determined sound source according to the difference of intensity, given the different paths established up to the sensor.
