A Study on Optimization of Fourth-Order Fading Memory Filter under the Highly Dynamic Motion of Both Own Ship and Target

Tracking filter plays a key role in accurate estimation and prediction of maneuvering vessel’s dynamics. The third-order α-β-Υ filter is one of the special cases of the general solution provided by the Kalman filter. Fading memory algorithm performs a better performance in numerous of α-β-Υ filter algorithms. This study aims to optimize the fourth-order fading memory algorithm α-β-Υ-η filter, which is extended form α-β-Υ filter, to get much more accurate position of high dynamic target on the condition that the own ship is also high dynamic.
