Abstract Tactical missiles extensively adopt combined guidance technology to enhance performance, using air handover strategies as their key technology. The traditional method employs Monte Carlo offline statistics to obtain the handover probability at a single time and online adjusts the seeker’s direction and search strategy, which requires a large amount of simulation and can only be used for preset operating conditions. Considering the above, this paper proposed an online evaluation method for missile handover probability based on an error propagation model. Main error sources were selected to establish the propagation model. The model was simplified to realize online computation and beneficial to multiple and strong universality. Through simulation verification results, it’s found that the online evaluation method for handover probability can achieve a relatively accurate distribution of handover probability and pointing error under different ballistic conditions. In addition, the accuracy of the evaluation satisfies the requirements of engineering applications.
