By establishing the mathematical model of the active and free flight segments of the first and second stage missiles, the feasibility of estimating the position of the missile launching point through radar detection data is analyzed in this paper. Firstly, error of missile launch point estimation based on different measurement data are compared. Secondly, the effects of different missile types on missile launch point estimation are calculated. Finally, the Monte Carlo method is used to simulate the influence of radar measurement accuracy on the missile launch point estimation by adding measurement error to the ballistic data, especially the influence of missile first-to-two separation process on estimation of the missile launching point is analyzed which can in turn improve the accuracy of the missile launch point estimation.
