A Method for Estimating Target Acceleration and Its Use in a Missile Guidance Law

摘要

This report describes an algorithm for estimating target velocity and acceleration using radar and inertial sensor measurements as inputs. In order to determine the accuracy and benefits of such an estimator, the algorithm is incorporated into a missile guidance law. Through the use of a simulation, terminal miss distances are compared with a similar missile using proportional navigation. Simulation results indicate a reduction in miss distance when such an estimate is used because of the missile's ability to recognize and compensate more quickly for the target maneuver. (Author)
