摘要：

The ultrasonic wave propagation is affected by absorption and diffraction. The transmission line is used to simulate the propagation media in PSpice model. To take into account diffraction effects we used the model proposed by J. Johansson [11]. A set of Gaussian beam is used to simulate the radiated field allowing us to deduce the exact diffraction loss. The diffraction loss is incorporated into the transmission line model using the attenuation parameter G. Measurements have been performed using a pulse echo system transmitting in water. The measurements show good agreement with the simulation results.
