Abstract :
A method used for estimation of the position of a moving pulse emitter with constant pulse repeat interval by a single observer is studied. The performance of the estimator depends on the emitter trajectory. A specific trajectory that is symmetrical about the closest point of approach is considered. Under this condition the Fisher information matrix has a simple form. The Cramer-Rao lower bound is then derived
