Description

technical field [0001] The invention relates to the field of nondestructive testing, in particular to a phased array microwave imaging nondestructive testing device and method. Background technique [0002] At present, the non-destructive testing methods of structural parts mainly include high-energy ray (X-ray, gamma ray) non-destructive testing and ultrasonic non-destructive testing. The application of these two detection technologies and methods on traditional metal materials and structures is relatively mature and common, but there are obvious problems for the detection parts made of non-metal materials and non-metal composite materials that are increasingly developed: 1) high energy Radiographic nondestructive testing. A fixed site is required to ensure radiation protection; the density of composite materials is too low for X-ray energy, and defects are difficult to show; there are significant requirements for the direction of defects, and planar delamination defects, ...
