摘要

在时差法超声波测风系统中

风速的测量精度受到时间延迟估计精度、两超声波传感器的距离精度等的影响。在后者一定的情况下

测风精度对时延估计精度提出了更高的要求。对此

采用了一种基于权值检测的最小均方误差（LMS）自适应时延估计算法

从而实现了高精度时延估计。计算机仿真与实际测试表明:该算法的估计精度满足了所研制的超声波测风系统的设计要求

能够用于机场区域低空风场情况的监测。

Abstract

In the ultrasonic wind measurement system using ravel-time-difference method

the precision of wind velocity measurement is greatly affected by the precision of time delay estimation

the precision of ultrasonic transducer distance.Requiring a more accurate estimation of time delay when the distance accuracy is fixed.In this regard

a LMS adaptive time delay estimation algorithm is adopted based on weight-coefficient detection

in order to achieve a high precision time delay estimation.Computer simulation and practical tests show that the estimation accuracy of the algorithm meet the requirements of ultrasonic wind measurement system.This algorithm can be used for monitoring the low-level wind field at airport regional.
