3D target reconstruction based on the ISAR image sequence

Aiming at the target recognition problem of the ISAR image, we propose a 3D reconstruction method based on the ISAR image sequence. The reconstruction process involves two steps: image matching and reconstruction. In image matching, target corners are premarked and sorted following the same order for all ISAR images. Projection transformation is then applied to establish pixel correspondence between the reference ISAR image and the other images. In reconstruction, a factorization method is carried out to obtain the 3D coordinates of every pixel of the target. Our simulation experiment of a cuboid and satellite demonstrates the efficiency of proposed method.
