英文摘要	Based on the general geometric model of multi-baseline synthetic aperture radar tomography (tomosar), the three-dimensional (3-d) sampling criteria, the analytic expression of the 3-d point spread function (psf) and the 3-d resolution are derived in the 3-d wavenumber domain in this paper. considering the relationship between the observation geometry and the size of illuminated scenario, a 3-d range migration algorithm with elevation digital spotlighting (rma-eds) is proposed. with this algorithm 3-d images of the area of interest can be directly and accurately reconstructed in the 3-d space avoiding the complex operations of 3-d geometric correction. finally, theoretical analyses and simulation results are presented to demonstrate the shift-varying property of the 3-d psf and the spatial-varying property of the 3-d resolution and to demonstrate the validity of the 3-d rma-eds.
