基于数字干涉仪的无源测向技术研究

Passive Target Location with Bearing-only Measurements Technology Research Based on Digital Interferometer

提出了基于数字干涉仪测向技术的无源测向定位系统,简述了其工作原理和工程实现方法,对高精度数字鉴相和宽带数字干涉仪基线配置及解相位模糊等关键技术进行了阐述,并给出了系统性能测试结果及与国外相关系统的情况对比。

This paper advances passive target location with bearing-only measurements system based on digital phase detector and briefs its working principle and engineering method. Then, it analyzes such key technologies as the baseline configuration of high-precision digital phase detector and wideband digital interferometer and phase unwrapping. The tested results of their system performance are given and compared with relevant systems abroad.
