Abstract :
In this paper, a three-dimensional (3-D) F-SAR imaging algorithm is introduced for Forwarding-looking SAR (F-SAR) data processing. The algorithm is the extension of the two-dimensional (2-D) range stacking algorithm (RSA) and allows the accurate image reconstruction without any interpolation and geometric correction. Then the spatial-varying and spatial-shift properties of the 3-D spread point function (PSF) of Forwarding-looking SAR are revealed with the analytical expression. Finally, the simulation experiment is performed to demonstrate the validity of the 3-D RSA.
