| 摘 要： | 从天线结构出发，主要阐述分析了近场情况下的信号特征，根据天线路径差来分析不同距离下的信号分布，找出理想监控距离，并推断出监控天线的高度。对比分析了理想监控距离附近的信号分布规律，同时对远场信号分布特征进行阐述，并与近场特征展开差异性对比，通过理论计算建立近场监控位置与远场信号的关联。最后列举在特殊情况下上坡地形和偏置安装时的监控设置。

| Abstract: | From the aspect of antenna structure and the near field signal characteristics, the distribution of signals in near field is discussed. The ideal monitor height and distance is achieved according to route error of different antennas. The ideal signal distribution is also discussed and compared with the circumstance in far field. Forward slope and bias installation of monitors in special situations is analyzed last. |
