摘要:

针对传统的相位干涉仪无法进行同时信号测向的问题,提出了一种基于相位干涉仪的同时信号测向方法,在干涉仪测向中引入了数字信道化技术来解决同时信号分辨,同时采用多基线天线结构来提高测向精度。通过理论分析及仿真实验,验证了该方法可实现同时信号测向的能力。

Abstract:

In view of the fact that traditional phase interferometers are incapable of simultaneous signal DOA estimation,a simultaneous signal DOA estimation based on phased interferometer is presented.The digitalchannelized technology is introduced to solve simultaneous signal detection,using multi baseline antenna structure to improve the direction of arrival (DOA) precision.Theoretical analysis and simulation experiment show that simultaneous signal DOA estimation can be realized by this method.

Key words: phased interferometer;digitalchannelized;simultaneous signal;DOA
