Quasi-optimal processing simulation of ultrasonic signals

Abstract

Magnetostrictive level gauges are widely used for measuring the level of bulk material and liquid medium including petroleum products, which determines the relevance of the measurement techniques and level gauges design improvement examination. The research objective is to modify the optimal signal processing classical methods for measuring the time intervals in the magnetostrictive level gauges by using the digital devices with limited computational resources. The article deals with the modification problems of the digital signal processing optimal algorithms providing the real time measuring devices operation. For addressing the challenges, the methods of numerical simulation and statistical processing of ultrasonic signals are used. Digital signal processing quasi-optimal algorithms for calculating the time intervals based on the use of cross-correlation functions leading to the operations number reduction, are described. The represented results can be applied in the level measurement and medicine for electrocardiograms analysis.
