In the research on complex maneuvering underwater target tracking, the single fading factor adjusts the estimation of all the state variables with the same value. However, the uncertainty of different state variable is different. Only one single fading factor can not get each state variable optimal estimation. Aiming at this problem, multiple fading factors strong tracking SCKF algorithm is proposed. Simulation results show that the multiple fading factors strong tracking SCKF algorithm has higher estimation accuracy than the CKF algorithm, SCKF algorithm and STSCKF algorithm when the underwater target system model is uncertain.
