Nowadays, localization of moving objects has attracted a lot of attention. In this regard, several algorithms
to detect and track various objects are presented. As an example, localization by measuring the time
differences of arrival signals (TDOA) can be mentioned . This method which is used in passive radars is
based on the time differences between the signals sent from the transmitter to a number of different receivers.
The purpose of this research has been to implement TDOA method and select the optimal method to
estimate the system error and evaluate its ambiguity. According to the arguments presented in this manuscript
Circular Error Probability criteria (CEP) is introduced as a criterion for the evaluation of performance
of TDOA based radars, and finally optimized site positions are developed to achieve the lowest error
by means of this criterion. Simulation results show improved performance of criterion selection on optimizing
topology and accurate localization of TDOA radars, consequently.
