A fourth-order extended Kalman filter is described which generates an estimate of target lateral acceleration. This is used with the sensed rate of change of bearing, the missile lateral acceleration, and its first derivative to generate a demanded lateral missile acceleration according to a precomputed suboptimal control law. Single-plane analysis is used throughout. The simulation results show that a substantial improvement in miss distance is achieved. This work concerns only target maneuver detection and no conclusions can be drawn about the effects of errors in the measurement of range and its rate of change.
