An Improved FastIMM Algorithm Based on α-β and α-β-γ Filters

摘要

In this paper, an Improved FastIMM algorithm is presented by optimizing the acceleration gain factor y and tracking indicesλof the α-β and α-β-γ filters. In this algorithm, a better acceleration gain factor γ is selected to improve the FastIMM filter's performance in target tracking. Besides, to get the appropriate ranges for tracking indices of the α-β and a-p-y filters, numerical simulations are carried out and the Root Mean Square Error (RMSE) of the position and velocity are analyzed. Simulation results show that the Improved FastIMM has much higher tracking accuracy while keeping the same computational burden.
