Abstract :
A forward-looking planar aperture based 3D observing model is set up. Under the lossless soil supposition, the dispersion and refraction of the earth is analyzed numerically. Then the conclusion is arrived that dispersion and defocus are trivial and the 3D image drift is obvious but deserve no correction. The 3D imaging is computation intensive. Based on the aperture factorizing and image area splitting principle, the 2D Fast Factorized Back Projection(FFBP) is extended to 3D FFBP, and the 3D imaging speed is boosted greatly.
