Damage detection method, damage detection device and terminal of phased array antenna

The present invention, which is suitable to the technical field of damage detections, provides a damage detection method, a damage detection device and a terminal of a phased array antenna. The damagedetection method comprises: obtaining a damage two-dimensional image corresponding to a damage front of a target phased array antenna and matching the view of the damage two-dimensional image with apreset reference three-dimensional model to determine a reference two-dimensional image corresponding to the damage two-dimensional image, wherein the reference three-dimensional model is built basedon a reference phased array antenna corresponding to the target phased array antenna and comparison of characteristics is performed on the damage two-dimensional image and the reference two-dimensional image to obtain a damage characteristic matrix of the damage front. The present invention can obtain damage situation of the phased array antenna timely, so as to provide an accurate basis for timely repairing the damage of t
