摘要
多波束比幅测向和干涉仪测向是现代雷达侦察告警系统中广泛采用的测向技术,论文对其工作原理和误差原因进行了分析,着重研究了测向模糊和测向精度的解决和提高方法,通过比较其在不同作战环境下的适用性,对信噪比的影响进行了仿真分析,并研究了量化后的数据特点,进而提出了一种新型的融合测向方法,设计了天线阵布置图,研究了其具备的优势特点并从实际舰艇电子对抗作战条件出发分析了融合测向方法的适用性。
The multi beam amplitude comparison direction finding and interferometer direction finding are the widely used di-rection finding techniques in modern radar reconnaissance and warning systems.The working principle and error reason of the two di-rection finding methods are analyzed in this paper.The paper focuses on the solution and improvement of the direction finding ambi-guity and direction finding accuracy.By comparing its applicability in different combat environments,the paper simulates and ana-lyzes the influence of signal to noise ratio and the quantitative data characteristics are studied.Furthermore,a new fusion direction finding method is proposed and the antenna array layout is designed.The advantages and disadvantages of the fusion direction find-ing method are studied and the applicability of the fusion direction finding method is analyzed under the actual electronic warfare conditions.
