摘要
介绍了干涉仪测向理论,描述了原始相位差样本的概念,阐述了相关干涉仪测向原理,给出了该测向体制下的目标函数模型,针对函数模型中原始相位差样本的求解问题,结合目前常用的测向天线阵列,提出了几种原始相位差样本的求解方法,分别从阵列流形、天线响应和相关表采集3个方面对不同体制及结构布局下的相位差样本的推导进行了论述,分析并总结了各种方法的特点及适用条件。
This paper introduces the theory of interferometer direction finding,describes the concep- tion of original phase difference sample,expatiates the direction finding principle of correlation in- terferometer,presents the object function model in this direction finding system,aiming at the sol- ving problem of original phase difference sample in the function model, brings forwards several sol- ving methods of original phase difference sample combined with current direction finding antenna array, discusses the derivation of phase difference sample in different systems and structural layouts from three aspects of array manifold, antenna response and correlative table collection, analyzes and summarizes the features and applicable conditions of each method.
