Abstract：Since human computation is complex and algorithm verification is difficult for ultrasonic testing in the air ,a rapid ultrasonic testing simulation method in the air based on tracing method is proposed .The proposed method utilizes CAD software for three‐dimensional modeling of the target object ,imports the OpenGL environment under the Microsoft Visual Studio C+ + by STL file format ,completes the reading and redrawing of STL models .Then ,it traverses the reflection points of the target object reflective surfaces ,adopts ray tracing law to identify the reflective sound ray according to ultrason‐ic wave propagation model in the air and Snell's law ,superposes the pressure of sound ray ,obtains the echo response signal of ultrasonic receiving array driving by the transmitting signal from different sound ray pressure of superposition on receiving array .Simulation results coincide well with theoretical analysis ,and provide the foundations to research ultrasonic testing in the air and related algorithms .
Keywords：ray tracing methodthree-dimensional modelingsound pressure of superposition
