Sensitivity of Track Velocity Error to Data Registration and Dynamic Errors within a Distributed System
Abstract
The success of accurately tracking an aerospace object is strongly dependent on how well the position, velocity, and acceleration of the object is known. Understanding what contributes to errors in these quantities, and how, is important in predicting the performance of a tracking system or as in the case of a Single Integrated Air Picture (SIAP) a distributed tracking system. A previous JSSEO Technical Report investigated position estimate errors as a function of data registration and dynamic errors. The Technical Report is a complement to that earlier analysis and outlines a similar methodology for understanding and investigating track velocity estimate errors. The study of velocity estimate errors is relevant not only to the general problem of aerospace object tracking, but also to the analysis of specific operational threads. For example, in an Integrated Fire Control(IFC) engagement, the interceptor will use positional and velocity information about the target. Therefore, knowledge of the errors in both the position and velocity estimates is important to predicting system performance.
