Bistatic Three Dimensional Interferometric ISAR Image Reconstruction

You are here

A three-dimensional (3D) bistatic inverse synthetic aperture radar (ISAR) imaging method is proposed in this paper. The proposed method makes use of interferometry and, technically speaking, produce a 3D target reconstruction by estimating scattering center position in a 3D Cartesian space. The proposed method makes use of a combined ISAR/ interferometry technique that allows also the ISAR image plane to orientation to be estimated. Cross or L shaped antenna configurations are discussed and the effects of the baseline length along the horizontal and vertical direction on the scatterer’s position estimation are analyzed in details. Finally, numerical simulations are used to evaluate the proposed method’s performance.
