Some target tracking filters ignore the radar range rate measurements because they are highly nonlinear in Cartesian space. A linearized measurement equation, composed of range rate's partial derivatives with respect to the track state, is sometimes used in an extended Kalman filter. Unfortunately, this naive linearization biases the posterior estimates.… (More)

Tracking maneuvering targets with radar is complicated because radar cannot measure target accelerations. We use the range rate measurement to calculate a new statistic that is a surrogate measurement of target acceleration under a coordinate turn model. Its distribution is found via simulation. A threshold test of the statistic turns out to be a reliable… (More)
