| Abstract: | We have investigated a location precision model based on the separated error of TDOA from that of station site by analyzing the principle of tri-station united TDOA location towards emitters.The scale of 2-D location error caused by target height is estimated as well.With the help of computer simulation,we have made some useful conclusions about the distribution of location error and station deployment.Then a location precision reckoning model is proposed. |
