REPRESENTATIVE STILL IMAGE DETERMINATION DEVICE FOR DETERMINING REPRESENTATIVE STILL IMAGE, PROGRAM AND RADAR DEVICE, AS WELL AS AIRCRAFT HAVING RADAR DEVICE LOADED

摘要

PROBLEM TO BE SOLVED: To automatically determine representative still images to be used for categorizing targets photographed in an ISAR video image.SOLUTION: A representative still image determination device 50 for determining representative still images to be used for categorizing targets photographed in an ISAR video image from a plurality of ISAR still images to be extracted from the ISAR video image comprises: a count unit 55 that targets a boundary between adjacent pixels as to all pixels of the ISAR still image, and counts the number of boundaries in which a luminance difference between the adjacent pixels is equal to or larger than a predetermined threshold; and a representative still image determination unit 56 that determines the ISAR still image in which the number of counted boundaries is maximum of the plurality of ISAR still images as a representative still image.SELECTED DRAWING: Figure 2
