摘要
文中基于传统的干涉仪测向的原理,并结合干涉仪消除测向相位模糊,实现了对跳频通信系统的无源测向方法。在此基础上,利用多单元园天线阵,实现了一种新的改进相关干涉仪方法。在仿真的基础上,对两种测向方法进行了分析比较,给出了两者测向的一些具体结果。
Based on the traditional theory of the interfemeter direction finder which can clarify phase ambiguity, this paper first realizes direction finding of hopping telecommunication systems and then realizes a new method for improving the interfemeter direction fingder on circular arrays. An emulation of the experiment is made, on the basis of which a comparison between the two methods is made with some outcomes presented.
