基于TDRSS阵列天线的目标跟踪算法

采用基于跟踪与数据中继卫星系统构建的天地一体化遥测、跟踪与指挥系统，不仅能有效地提高遥测、跟踪与指挥的覆盖率、定轨精度、飞行器全程测量和对多目标的同时遥测、跟踪与指挥能力，而且能够完成各类对地观测卫星的高速实时数据回传的任务。与常规的测控系统不同的是，中继星的遥测、跟踪与指挥是在地球这一复杂的背景环境下进行的，因而会受到各种各样的干扰。采用阵列天线对目标进行自适应跟踪可以实现空域滤波，使信号得到加强，干扰得到抑制。采用Matlab软件仿真了中继星对目标星的跟踪过程，并对两种经典的自适应跟踪算法（LMS，DMI）进行了研究。通过分析信号干扰比的变化，比较两种算法的跟踪性能。

Target Tracking Algorithm of Array Antenna Based on TDRSS

The integrated space-earth telemetry,tracking and commanding(TT&C) system based on tracking and data relay satellite system(TDRSS) not only can effectively raise the coverage ratio of TT&C network,the precision of orbit determination,the all way measurement of spacecraft and the simultaneous TT&C capability for multi-object,but also can accomplish the high-speed real-time data relay of various types earth observation satellites.The new system differs from the ordinary TT&C system is that the TT&C of relay s...
