The object of the invention is to provide a new method for phased array ultrasonic detection beam synthesis - axial parallel virtual focus beam synthesis, phased array ultrasonic testing. Beam synthesis is a central part of phased array ultrasonic signal processing, and its fundamental significance is to form a scanning beam in a specific direction to detect imaging. The axial parallel virtual focus beam synthesis to form a specified direction of beam required for space, processing of signal and noise, can obtain spatial imaging resolution and high precision, but also can get the signal-to-noise ratio is large enough.
