Ultrasonic Wind Speed Measurement Using a Polygon Approximation for the Signal Envelope

摘要：

　　A new technique for the ultrasonic wind speed measurement is presented in this paper.This technique measures the start and end time for the received signal to be detected on a given threshold and calculates the delay based on a polygon approximation for the signal envelope.This technique needs a small count of computation and has a good accuracy and a wide dynamic band.
