For continuous-time nonlinear deterministic system models with discrete nonlinear measurements in additive gaussian white noise, the extended Kalman filter (EKF) covariance propagation equations linearized about the true unknown trajectory provide the Cram??r-Rao lower bound to the estimation error covariance matrix. A useful application is establishing the optimum filter performance for a given nonlinear estimation problem by developing a simulation of the nonlinear system and an EKF linearized about the true trajectory.
