LEON-MARTINEZ, Javier A.; HERNANDEZ-GOMEZ, Antihus A.  y  IGLESIAS-CORONEL, Ciro E.. Mathematical Modeling and Analytic Characterization of an Ultrasound Proximity Sensor. Rev Cie Téc Agr [online]. 2020, vol.29, n.4, e01.  Epub 01-Dic-2020. ISSN 2071-0054.

This research work is about mathematical modeling and analytic characterization of a proximity sensor prototype based on ultrasonic acoustic echolocation with thermal compensation. The analytic characterization of the propagation medium behavior under the acoustic disturbance produced by the sensor is presented, starting from a correlation function fitted to the real excitation signal generated by it. The influence of the catoptrics conditions of the separation boundary between the air and a set of materials in echo intensity is also referred. Likewise, the sensor response to the echo (considering the worst catoptrics conditions) is analytically characterized.

Palabras clave : ultrasound sensor; acoustic excitation; acoustic reflectivity coefficient; echo intensity.
