Paper Abstract

This paper proposes a new image registration method based on grade-by-grade matching in interferometric inverse synthetic aperture radar (InISAR) imaging system using two antennas. The causation and quantitative analysis of the offset between two ISAR images for different antennas along each baseline is analyzed. Strong scatterer centers (SSCs) are extracted from the ISAR images of each antenna by OTSU method firstly. A standard matching is calculated by the image centroid. Then a mapping of region of interest (ROI) and correlation is carried out to get the precise registration. Simulation results demonstrate that the offset between two ISAR images can be compensated effectively when the proposed method is used, achieving a high quality 3D InISAR image consequently.
