实时相位校正在多基线干涉仪测向系统中的应用

Application of Real-time Phase Correction to Multi-baseline Interferometer DF System

介绍了多基线干涉仪测向原理,提出了一种解决通道相位不一致的校正技术。与传统的方法不同,该方法在变频通道前增加自检信号源,实时记录并存储通道间的误差,用以校正。此方法已应用在某小型化侦察设备中,并取得了良好效果。

This paper introduces the direction-finding principle of multi-baseline interferometer, brings forward a correction technology to solve the channel phase variance. Different from tradi- tional methods, this method adds a self-test signal source in front of the frequency conversion chan- nel to record and store the errors among channels in real-time for correction. This method has been applied to a certain miniaturization reconnaissance equipment and obtained perfect effect.
