3-D Imaging Methods for Highly Squinted Tomo-SAR on Accelerated Motion Platform
This paper studies the three-dimensional imaging method for tomography synthetic aperture radar (Tomo-SAR) on accelerated motion platforms operating in highly squinted imaging mode. A new method using the nonuniform fast factorized back-projection (NUFFBP) algorithm is proposed to tackle the accelerated issue. The elevation resolution is achieved by utilizing array antenna in this paper. The compressive sensing (CS) theory is adopted to achieve the super-resolution in elevation direction. The SAR imageries in the range and azimuthal directions, combined with the elevation resolution, construct the three-dimensional (3-D) SAR image. Simulated data results show the good performance of the method.
