In this paper is presented the procedure to wind speed measurement based on ultrasonic sensors. For this purpose the ultrasonic Time-of-Flight (ToF) was estimated using the DFT (Discrete Fourier Transform) technique. The analysis of the influence of multiplicative and additive noise of the medium into the DFT is carried out. Then, the uncertainties propagation for ToF and wind speed measurements is...
This paper presents the procedures for the wind speed measurement using ultrasonic transducers. The wind speed measurement is based on the time-of-flight (ToF) ultrasonic estimation that has been estimated using the Extended Kalman Filter (EKF) algorithm. For this purpose it was developed the dynamic system model in state space and was analyzed the convergence of the EKF algorithm. Simulation results...
Hydrogen concentration measurement with low uncertainty is of great importance in industrial, scientific and commercial applications, which is directly related to the performance of the acquisition system and signal processing. For this purpose, in this paper, it is presented a procedure for the hydrogen concentration in air estimation, using ultrasonic transducers. The time of flight measurement...
