摘　　要：空间拦截要求进行拦截轨道优化,实现时间和能量最优。针对异面冲量拦截能量消耗大的现状,提出了在虚交点进行拦截的方式。应用普适变量法解决Lambert问题,从而实现拦截轨道的优化。与异面拦截相比,虚交点拦截不需要改变轨道面就可实现拦截,节省了能量。通过STK对拦截过程进行了仿真,证明了该拦截方式的可行性。In order to achieve the optimum time and energy,we need optimize the intercept orbit in space interception.For the circumstance that it needs more energy about plane change impulsive orbit interception,a new method was put forward about interception at virtual crossing point.The method of general variable law was adopted to solve the Lambert problem and it could achieve the optimum intercept orbit.Compared to plane change interception,the way of virtual crossing point interception needn＇t change the plane and reduce the energy.By STK simulation of entire process,it was proved to be right.
