SAR Tomography Imaging Based on High-Order Spectrum Analysis

摘要：

This paper, the issue of achieving real 3-D reconstruction of the 3-D scene is discussed to avoid the height blur in the conventional 2-D SAR imaging. By analyzing multiple pass (or antenna) system, the conclusion is drawn that the 3-D system can be realized with two 2-D imaging. The problem of aperture synthesizing in height direction is presented, while conventional SAR image can be obtained with existed methods. The second aperture is synthesized in height with SPOTSAR mode by high-order spectrum analyzing. Finally, the actual imaging of the scene reflectivity is obtained through two apertures synthesizing. To validate the methods, several experiments are carried out using simulated data sets.
