Abstract:

It is shown that Kalman filtering may be applied to the radar track- while-scan problem. No attempt is made to rigorously derive the Kalman equations, but the equations are related to more familiar ideas. It is demonstrated that the least squares alpha beta equations constitute a special case of the Kalman filter. The approach used, however, does not require a constant data rate or constant measurement accuracy, meaning that information from various sensors including links may be used.
