摘要
提出了一种基于 DBF和 DMF- CDMA技术的多飞行器测控系统。首先描述了系统的工作原理。然后对 DBF给出了全面和详细的计算机仿真 ,包括圆面阵 DBF阵因子方向图彷真和 DBF对多飞行器的搜索与跟踪仿真。最后对 DMF- CDMA给出了实验结果。实验的硬软件已达到实用水平。这些说明本文提出的多飞行器测控方案是可行的。
In this paper,a kind of TT&C system of multi vehicle based on DBF,DMF CDMA is proposed.Firstly the principles of this TT&C system are described .Secondly the computer imitations of DBF are given indetail.The imitations include the imitation of antenna pattern of the circular array,the imitation of that DBF searchs and tracks the multi vehicle.Finally the experiment results of DMF CDMA for multi vehicle are given.The above discussions prove that the TT&C system proposed by this paper is practicable.
