N2 - In this paper, a pseudo measurement model is adopted to deal with the Kalman filter problem with color measurement noise. It is assumed that the measurement noise is color, and be described by AR(n) model. The state equation is set up according to Singer's model. The measurement equation is set up in polar coordinate and the range rate measurement is combined with ordinary data (i.e. there are four measurement data now: range r, azimuth θa, elevation θe and range rate r). By means of proper coordinate transformation, the matrix of Kalman gain and the matrix of filter error covariance will be decoupled. So that the computing requirement of the algorithm will be reduced and can be performed in real time.
