Firstly, from Gauss' equations and relative motion equations, the relation of control impulse and relative motion was expressed as analysis formulas and simplified based on the near circular condition. By deeply analyzing the mechanism of impulses in each directions (radial, in-track and cross-track directions) effect on relative motion respectively, two maneuvers to establish formation flying are provided: one is to utilize the impulses in radial and cross-track directions, the other is to utilize the impulses in along-track and cross-track directions. Both of the two methods can establish satellite formation flying of any configuration. The method with impulses irradial and cross-track directions needs only 3 impulses, while the method with impulses in along-back and cross-track directions needs 4 impulses. Lastly, by an example of establishing a space-circle formation flying, two maneuvers were compared with each other in the amount of impulses and fuel consuming estimation.

首先由高斯型拉格朗日轨道摄动运动方程得到轨道坐标系中控制冲量与轨道根数偏差的关系，基于近圆轨道的条件简化并带入相对运动方程，得到控制冲量与相对运动的关系表达式；通过深入分析各个方向（径向、沿迹向与轨道面法向）的控制冲量对相对运动的影响，给出了分别用径向与轨道面法向控制冲量组合和沿迹向与轨道面法向控制冲量组合实现编队捕获的两种控制策略；最后给出了一个空间圆编队捕获实例，并从燃料消耗、施加冲量次数及捕获时间等角度对比研究了两种控制策略的特点。

The main contributions of this paper include,(1) introduces the backtracking mechanism into traditional GEP methods and proposing a new algorithm named GEP with backtracking strategy.(2) Proposes the concept of Backtracking Checkpoint and designing Geometric Proportion Increased Checkpoint Sequence and Accelerated Increased Checkpoint Sequence to restrict the backtracking process.(3) Extends the GEPBS algorithm by introducing a Retrogression Factor to control the percentage of backtracking.(4) Proves the effectiveness of the new algorithm by two extensive experiments, which show that new method increases the max fitness by 49.2

本文的主要工作包括：（1）在传统GEP算法中引入回溯机制，提出基于回溯策略的GEP算法（GEP with backtracking strategy ，GEPBS）；（2）提出回溯检查点概念，设计了等比递增检查点序列和加速递增检查点序列用于约束回溯过程；（3）扩充基于回溯的GEP算法，设计了退化因子，提出了按比例回溯策略（GEP with proportional backtracking strategy， GEPPBS）（4）通过两个实验验证了新算法的有效性，在相同条件下较传统算法的适应度最大提高了49.2％，成功率最高提高了4倍

The goal-keeper use dynamic defence strategy is superior to a single strategy in field experiment and competition.

利用动态策略的守门员在实地实验和实际比赛中效果明显优于单一策略

Goal-keeper defence strategy of traditional Mid-size Group are used to use single geometric algorithms that difficult to adapt to field movement and ball trajectories and state in competition.

中型组守门员多是从单一的几何算法角度上考虑守门员的防守策略，在实际比赛中，场上形势变化快，足球运动轨迹和状态不规则，单一的防守策略较难适应场上变化。

Goal-keeper use dynamic decision according to football state, football respective districts, goalkeeper stations and other information in field that make up a single strategy in real-time defence and effectively improve the goalkeeper.
