基于虚拟基线的相位干涉仪阵列优化设计

Optimum Design of Phase Interferometer Array Based on Virtual Baseline

针对6~18GHz频带内的辐射源信号,在阵列天线阵元等间距布置条件下,采用基于虚拟基线的优化配置算法,分别对阵列天线总阵元数一定时满足解模糊条件所需的最少干涉仪测向信道数,以及干涉仪测向信道数量给定时满足测向精度所需的阵列天线最少阵元数进行了仿真分析,对干涉仪测向系统实现具有一定的工程应用价值。

The optimal allocation algorithm based on virtual baseline is adopted for emitter signal of6~18 GHz.When the distance among array elements is equal constantly,the minimum number of interferometer direction finding(DF)channel required to satisfy the ambiguity resolution condition is simulated and analyzed,and when the number of interference DF channel is constant,the minimum number of array antenna element required to satisfy the DF accuracy is simulated and analyzed.Above analysis has definite engineering application value for interferometer DF system.
