物位计测量技术分析及应用研究

Analysis and Applicable Research on Level Measurement Technology

雷达物位技术是物位测量技术中发展较快的技术之一,但我国雷达物位仪表的研发还比较落后。分析了雷达物位计市场所占比重最大的两种测量方式——雷达脉冲测量和连续波线性调频测量的信号处理方式,比较了它们各自的优缺点,并指出了在应用中应注意的问题;同时,探讨了物位计开发过程中的技术难点,并根据我国现有的技术条件提出了相应的解决方案。

The technology of radar material level measurement is the faster developing area in material level measurement,but the development of such radar instruments of this area is comparatively slow in our country.Thus,in accordance with two of the measuring modes occupied most of the market of radar level meters,i.e.radar pulse measurement and continuous wave linear frequency modulation measurement,their signal processing patterns are analyzed in detail,and their merits and demerits are compared respectively.The cautions in applications are pointed out.In addition,the technical barriers in development of the material level meters are investigated;and related solutions based on existing technical conditions in our country are given.
