Passive Range Estimation for Antishipping Missiles

Abstract

This report deals with several techniques for passive ranging, i.e., the estimation of target range from noisy measurements of bearing or line-of- sight angle alone. The type of engagement treated in this investigation involves a maneuvering surface target and a missile without an altimeter. The missile approaches the target along a trajectory that is characterized by a low- altitude cruise phase followed by a terminal pitch-up maneuver. Several modified Kalman filter-like algorithms are applied to this nonlinear filtering problem; these include the extended Kalman filter (based on small-signal linearization) and several quasi-linear Kalman filters (based on random-input describing function theory). Performance comparisons are obtained by applying the filters to a number of trajectories.
