摘　　要：针对极端对抗条件下航天应急发射机动测控能力难以量化评估的问题,提出了一种基于有限方向随机游走的火箭发射测控机动布站方法,以最大测控覆盖和最小站间重叠为目标,通过多机动站站间重叠情况限制站址随机游走方向,迭代优化生成最终机动部署方案。仿真结果表明,所提方法在给定火箭弹道下能够有效确定任意数量机动站部署位置,在测控覆盖率、站间重叠率、站址接受率等方面均优于对比方法,当机动站数量大于5时,对典型火箭弹道的测控覆盖率达到98%以上,相对于正常发射情况下全段测控要求,可有效支撑航天应急发射实施。Since it is difficult to quantitatively evaluate the mobile telemetry,tracking and command(TT&C)capability of space emergency launch under extreme confrontation conditions,a mobile deployment method for rocket launch TT&C stations based on random walk in finite direction is proposed.With the maximum coverage rate of TT&C and the minimum overlap rate between stations as optimal goals,the random walk direction of a station is limited according to the overlap between multiple mobile stations.The final deployment scheme of mobile stations is iteratively optimized.Simulation results show that the proposed method can effectively determine the positions of any number of mobile stations with a given rocket trajectory,and performs better than the comparison method in terms of coverage rate of TT&C,overlap rate between stations,acceptance rate of station,etc.When the number of mobile stations is greater than 5,the coverage rate of TT&C for typical rocket trajectory can reach more than 98%,which can effectively support space emergency launch compared with the full-section TT&C requirements under normal launch conditions.
