地面测站引导卫星逆向交会的交会角研究

Study of rendezvous angle of counter orbit satellite intercept based on ground TT&C station

建立了用地面测控站引导交会时,不同交会角条件下测量误差引起的交会脱靶量计算模型和交会概率计算模型。重点讨论了单站雷达测量、双站雷达测量时,以最大交会概率为优化目标时的最优交会角问题,并确定了雷达测站位置与最优交会角的关系。仿真结果表明,最优交会角的恰当选择能显著提高逆轨卫星交会概率。

Based on the ground TTC（Tracking telemetry and command） system,the miss distance error calculation model and the intercept probability calculation model are given.The optimal rendezvous angle is discussed to gain the max interception probability measuring with single TTC station or double TTC stations.At last,the relationship of TTC position and optimal rendezvous angle is presented.The simulation result shows the optimal rendezvous can bring up the counter orbit satellite interception probability.
