The Utilization of Data Measurement Residuals for Adaptive Kalman Filtering
Abstract
In recent years, the Kalman filter has been used extensively for passive target motion analysis (TMA) -- an application in which filter divergence is a common problem. Available methods for eliminating divergence ultimately involve increasing filter sensitivity by discounting the influence of past data. However, this procedure makes the filter more susceptible to random errors; therefore, to avoid unnecessary sacrificing of noise performance, adaptive control is required. In this report, the Kalman filter equations are derived and the associated data measurement residuals are examined to determine their suitability for providing adaptive control. An important relationship between the system performance index and the data residuals is established.
