- W4382644368 abstract "Internal damage detection technology of composite materials is one of the hot topics in the field of materials research. Millimeter wave has the advantages of high resolution, penetration and high safety, and has great potential for nondestructive testing of composite materials. This paper studies the feasibility of millimeter-wave detection of composite material damage. The mechanical scanning method of horn antenna is selected. A motion control module for mechanical scanning and a 35GHz radar imaging technology based on wave-number domain algorithm are introduced. The motion control module uses the data acquisition card to transmit the control signal and realizes the step motion control and direction control of the mechanical scanning guide rail. Based on wave-number domain radar imaging technology, a point target simulation program of two dimensional coronal plane and cross section is written. The target scattering point model is established by simulation, and the target position can be reconstructed clearly after processing by wave-number domain radar imaging algorithm. The imaging resolution is quite high, which verifies the feasibility of damage detection of composite materials based on millimeter wave and lays a foundation for the further development of composite material nondestructive testing equipment." @default.
