一种具有高稳定鉴频零点的零频鉴频系统分析与设计

Analysis and design of a zero—beat frequency discriminating system with bigh stalility of zero deviation point

本文对机载动显雷达(AMTI)的主瓣杂波频率跟踪系统的两种方案进行比较之后,阐述了一种具有高稳定鉴频零点的零频鉴频系统的原理。对设计电路的要素以及降低零点漂移的方法作了介绍。给出了应用本系统获得的科研成果。

After making a comparison between two schemes of mainlobe clutter tracking system in AMTI radar,the paper expounds the principle of a zero-beat frequency discriminating system with high stability of zero deviation point.The essentials of designing circuits and the methods of decreasing the drift of zero deviation point are introduced.The achievement in the scientific research using the system is given.
