MODELING THE ULTRASOUND WAVE PROPAGATION IN THE SOLID BODY BY THE HARDWARE

Abstract

The improved ultrasound propagation wave modeling algorithm is proposed, which consists in representing the medium in the form of a system of the wave digital filters. The algorithm differs in that due to the implementation of the multichannel filters with the programmable delays, the simulation error of the sound propagation dispersion is decreased. The algorithm implementing in FPGA provides the modeling in real time.

Key words: FPGA, sound dispersion, wave digital filter.
