| 摘 要： | 针对现阶段油水界面液位测量方法的测位精度低、可靠性差等问题,提出雷达测量油水界面液位的方法,介绍了使用雷达测量油水界面液位的原理和设计方案。同时,对信噪比较低时,液位信号的精度不高问题,提出使用Rife结合Quinn的方法估计信号频率。仿真结果表明,该算法的均方根误差较小,估计性能优于传统的Rife法和Quinn法。

| Abstract: | According to the problem of current level measurement method of oil-water interface low accuracy and reliability,a radar measurement method of oil-water interface level was proposed.The principle and design scheme were introduced.At the same time,the method of using Rife with Quinn to estimate signal frequency was put forward to solve the problem that liquid level was low precision when signal to noise ratio（SNR） was low.Simulation results show that root mean square（RMS） error of this algorithm is smaller;estimation performance is superior to the traditional method of Quinn and Rife. |
