一种改进的干涉仪测向基线设计方法

An Improved Method of Interferometer DF Baseline Design

在原有干涉仪测向基线逐级解模糊规则的基础上,在工作频率、无模糊视角范围及相位差误差等条件下,为达到利用较少的天线阵元数解最长基线模糊的目的,提出了一种改进的干涉仪测向基线配置方法,并结合设计实例与已有基线配置方法进行比较,验证了本文的基线配置方法能达到更高的测向精度。

Based on the rule of gradually resolving ambiguity of original interferometer direction finding （DF） baseline,this paper puts forward an improved interferometer DF baseline deployment method for the aim of resolving the longest baseline ambiguity by using less antenna array elements under the conditions of operating frequency, range of no ambiguity view, phase difference error, etc. ,and compares the method with existing baseline deployment method combining with design example,proves that the baseline deployment method provided in this paper can fetch better DF accuracy.
