摘要：

In this study, an indirect method, named the combined shooting and collocation method (CSCM), is proposed to solve the accurate saddle point of the three-dimensional orbital pursuit–evasion (PE) game under J2-perturbed dynamics. With the analytical conditions for optimality used for both players, the CSCM can compute an accurate saddle-point solution. By decomposing the original two-point boundary-value problem (TPBVP) P into two layers and progressively handling the constraints, the developed CSCM can robustly find a saddle-point solution for a variety of orbital PE scenarios, even under J2-perturbed dynamics. The computation effort of the proposed method is below 50 iterations in practice.
