摘要

简要分析了调频雷达液位计的基本原理。提出了一种基于雷达调频和鉴相相结合的提高雷达液位计精度的新方法。该方法采用调频技术获取未知电平的粗糙数据，采用鉴相技术获取细微数据，然后将它们结合在一起得到高精度的电平组成数据。重点讨论了粗数据和细数据组成数据的有效条件。

A new method of high-accuracy level-measure based on combining radar frequency-modulation and phase-discrimination

The basic principle of frequency-modulation radar level gauge is analyzed briefly. A new method to improve the precision of radar level gauge is proposed based on combining radar frequency-modulation and phase discrimination. The method adopts frequency-modulation technique to get rough data of an unknown level, uses phase-discrimination technique to get subtle data, and then joins them together to get high accuracy composition data of the level. Effective conditions for data composition of rough data and subtle data are also discussed especially.
