捷变频雷达本振功率曲线多变原因分析

Analysis of the reasons for the variation of the LO power curve in Frequency Agile Radar

摘要:

频率捷变雷达(FAR)主要分为非相干与全相干2种，是公认的最具发展前途的雷达之一。本文结合试验中某型号非相参FAR本振功率遥测曲线多变现象，基于捷变频技术、本振系统、遥测读数等原理，分析了曲线多变的原因，并最终认定系统性能良好，解释了装备鉴定部门对该类产品核心性能的长期困扰，发挥了较高的工程效益。

Abstract:

Frequency Agile Radar(FAR) is recognized as the most promising radar，which is divided into incoherent and coherent types. Focusing on the varied phenomena of the remote sensing curves for Local Oscillator(LO) power in a certain FAR，this paper analyses the reasons of their variation during test basing on the Frequency Agile techniques, LO system, telemetry readings etc. The working condition of this LO system is proved to be in normal at last, which removes the long-standing worry about the key capability of this type of equipment from judge department，and exerts great engineering benefits.
