| 摘 要： | 分析了极化相同、时间上重叠的两点源信号(主信号和干扰信号)的干涉仪测向问题。给出了干涉仪测量这类两点源信号中的主信号入射角的通用数学表达式。简要讨论了几种特殊情况下同时到达的干扰信号对测向精度的影响。可供更多干扰信号条件下干涉仪测向问题分析和工程设计参考。

| Abstract: | This paper analyses the interferometric direction finding(DF) for certain signals of two transmitters,which include major signal and interference signal,with same polarization and time-overlap.Generel mathematical expression on incidence angle of major signal in such signals with the interferometer is presented.The effects of simultaneously arrived interference signal on accuracy of DF are discussed for several special cases.The results have some reference value for analysis interferometric DF in the case of mulit-interference signal and engineering design. |
