Obtaining the statistic characteristics of noises is the key point in the design of the all-integrator model Kalman filter (IKF).The setting of the statistic characteristics of noises has been studied in this paper.The function of the discrete statistic characteristics of noises and sampling period within the IKF has been derived.The tracking performance on the statistic characteristics of noises within the IKF has been quantitatively analyzed.On this basis,a method for calculating the statistic characteristics of noises by directly using roll-off frequency and discrete sampling period has been proposed,which overcomes the drawbacks of the traditional simulation-experiment-adjustment loop setting method and simplifies the design procedure.This proposed method is verified by simulations and experiments.
