Kalman filter design for target tracking in microwave rendezvous and docking radar

For tracking target aerocraft in microwave rendezvous and docking radar, radial distance and velocity in spherical coordinate system were tracked jointly by a 3rd order improved Kalman filter elevation and elevation rate, azimuth and azimuth rate were tracked by two identical 2nd order improved Kalman filters respectively. The parameter design of state noise in the application of Kalman filtering to the tracking was solved effectively by a proposed real-time estimating algorithm. The simulated results show that the proposed Kalman filter can accurately track target aerocraft, and has strong adaptation to target's dynamic.
