Özet

Electromagnetic, acoustic, or seismic sources can be positioned using direction, time, frequency or time/frequency difference of their transmitted signals. Source coordinates are found using time difference of arrival (TDOA) method that depends on the time differences of spatially separated receivers. In these methods, two different TDOA sets are used, including independent/spherical and full. In this study, positioning with particle swarm optimization (PSO) is achieved using independent set and full sets and positioning error is compared with Cramer-Rao lower bound (CRLB). In addition, it is proven that CRLB can be exceeded using the PSO algorithm that uses the full TDOA set.
