Time difference of arrival dilution of precision and applications
IEEE Transactions on Signal Processing, 1999Performance prediction for time difference of arrival (TDOA) systems that rely on standard covariance methods exhibit poor correlation with simulated results. A superior metric (TDOA dilution of precision (DOP)) is derived. DOP is familiar to Global Positioning System (GPS) users and, although the equations governing TDOA DOP are quite different ...

Digital Signal Processing, 2015
The problem of jointly estimating time difference of arrival (TDOA) and frequency difference of arrival (FDOA) or Doppler has a variety of practical applications. The conventional cyclic ambiguity function and the fractional lower-order ambiguity function suffer performance degradation in the presence of non-Gaussian α-stable impulsive noise and ...

Different perspective of time difference of arrival averaging
2012 35th International Conference on Telecommunications and Signal Processing (TSP), 2012Any emitter can be positioned using three or more receivers in two dimensional planes and four or more receivers in three dimensional planes. The transmitter signal reaches at the receivers that synchronized each other's in different times. Using this time differences of arrival (TDOAs) hyperbolic lines of positions (LOPs) are defined and target is ...
