Given sumption computation the minimum energy consumption of space based on weapon transfer, energy con- al model is built and an improved differential evolution algorithm which optimizes the transfer of energy consumption based on the schedule interception time is put forward. Simulation re- sult indicates that this algorithm has preferable stability and convergence, and the algorithm can search much better interceptor transfer time and corresponding energy consumption in less time.
