摘要/Abstract

摘要： 针对短波无线电测向场地选址困难的问题，提出了一种基于改进多信号分类（MUSIC）算法的短波非规则天线阵列测向系统.该算法可使短波无线电测向系统部署在地势平坦地区，还可以部署在山区、丘陵等复杂地形，有效解决了短波无线电测向系统的选址问题.在对该算法进行理论建模和计算机仿真验证的基础上，开发了短波非规则阵列测向原型系统，并在实际环境中进行了大量现场测试.测试结果表明，改进MUSIC算法具备了在非规则阵列条件下进行来波信号方位测定的能力，相应的非规则天线阵列测向系统能够在复杂地形条件下实现测向功能.

Abstract: Traditional high frequency (HF) finding system needs a large and plain area for antenna array, so it is difficult to find a suitable place for practical HF direction finding systems. To address this issue, an improved mutiple signal classification (MUSIC) algorithm is proposed for HF direction finding system with non-regular antenna array. This algorithm makes it possible to deploy HF direction finding system not only in plain area but also in the conditions of complex terrain, which makes it much easier to find a place to deploy HF direction finding system. On the basis of theoretical modeling and computer simulation, a prototype system of HF irregular array direction finding was developed and tested in the real environment. The experiment results showed that the improved MUSIC algorithm was available for direction finding in the condition of non-regular antenna array, and the corresponding HF direction finding systems can work well with complex terrain conditions.

Key words: shortwave, non-regular antenna array, improved multiple signal classification algorithm
