The spatial correlation of the multi-target tracking problem is described. The distribution error of measurement error in Cartesian coordinate system is obtained. A variable step size processing method based on error distribution is proposed. According to the statistical model of error, the center of the associated area is determined by Kalman filter and the corresponding simulation result is given
