Abstract

The use of driving-aid ultrasonic systems in low visibility conditions due to fog, makes it necessary to study the influence of environmental parameters such as temperature, humidity or air velocity on the ultrasonic propagation. The present work tries to construct simple empirical models for velocity and echo amplitude that includes temperature and relative humidity as inputs. We present the results obtained in the modelling of the ultrasonic propagation in environments with variable conditions of humidity and temperature, including foggy conditions
