Research and Realization of Correlative Interferometer Key Technology

详细分析相关干涉测向的各项关键技术,以五元圆阵为模型,说明天线超孔径对测向结果的影响及解决方法,分析相关算法,说明来波方向角的计算方法。最后讨论解决接收通道相位不一致的方法以及避免天线的来波信号被屏蔽的方法,并且编制出测向系统应对以上情况的基线选择判决流程。

This paper analyzes the terms of key technology of correlative interferometer in detail. Uses a five dipoles circular array as model to analyze the principle of interferometer direction finding in order to illuminate that the impacts on direction finding result with antenna over-aperture and the solutions. Meanwhile, it also analyzes correlative interferometer and illuminates the calculation for incidence azimuth. Finally, it discusses how to solve the problem of receiving channel noncoherent and how to avoid the effect on masked dipoles, then programs the base chosen procedure to handle the situation of hereinbefore.
