Comparison of Filtering Options for Ballistic Coefficient Estimation
Abstract
The capabilities of a linear decoupled Kalman filter and two extended Kalman filters were examined when tracking an object as it enters the atmosphere. The filters were given identical radar range and elevation data. The first extended filter estimates the position, velocity, and inverse ballistic coefficient; the second estimates position, velocity and the ballistic coefficient. The linear filter estimates position, velocity and acceleration and derives the ballistic coefficient from those estimates. The paper will show that the performance of the linear filter is inferior to that of the extended filters, while the performances of the extended filters are nearly identical.
