Abstract :
In the time difference of arrival (TDOA) problem, the unknown location of an emitter is estimated using a set of TDOA estimates. In this paper, a closed-form solution for a nominal TOA in the TDOA problem is presented for the case of three or four receivers that under certain conditions results in location estimates that are optimal in the least-square error sense.
