Ultrasonic testing is an important flaw detection technology in nondestructive testing field. With its unique electronic scanning, dynamic deflection focusing (DDF), sectorial scanning characters and ultrasonic phased array (UPA) technology can be used for defecting detection of objects with curved face or complex structure. Thus, UPA technology has become a focus of ultrasonic testing research. In order to solve a kind of problem of the internal inspection, this paper analyze methods of phasing array imaging and make a simulation scheme. The simulation result shows that the fan imaging method proposed by this article is right, establishing basis for the real-time imaging test analysis of ultrasonic flaw detection.
