空分加时分(空时分集)通信天线的跟踪问题研究

Research on the Tracking Problem of Communication Antenna under Time Division and Space Division

摘要:

在时分多址通信体制下,采用相扫天线是抗截获、抗干扰的最有效途径。在时分多址通信体制下解决相扫天线节点间相互跟踪和通信是关键问题。文中详细地阐述了计算补点的方法,分析了方位角、航向角、舷角与扫描跟踪角之间的关系,并给出了相应的数学模型和补点算法的过程。

Abstract:

Adopting phase-scanned antenna is an effective approach to anti-interference and anti-interception in time division multiple access(TDMA)communication system. It is a key problem which of inter-tracking and communication between inter-node antennas to be solved by phase-scanned antenna in TDMA communication system. The necessity of preventing node to be tracked from loss was discussed in detail in this paper, which based on the method of calculation interpolating. The relationship between azimuth angle, course angle, port-starboard angle and scanned-tracked angle was analyzed, and corresponding mathematics model and the process of interpolating algorithm were proposed.
