For identifying the target and estimating its attack attempt early to improve the intercepting efficiency in anti-missile battle, the information support about target is necessary and provided by space-ground warning system. Using an effective matching model can achieve detecting and affirming the target property quickly based on the information of target from the space-ground warning system. This text emphasizes on the matching model and the algorithm of target property and elementarily realizes the matching model of target property using emulation method based on the measuring model of space-ground warning system. The result indicates that the matching model and algorithm are of better value to application and can give some reference to the command and control system in construction and perfection.
