Abstract

The three-dimensional image quality of tomography SAR is limited by the non-uniform track distribution in repeat-pass data acquisition. In order to overcome the drawbacks of known methods caused by the non-uniform track distribution, a new three-dimensional imaging approach is proposed based on backprojection for tomography SAR in this paper. Raw data of tomography SAR in X-band is simulated and three-dimensional image is achieved. The imaging result is analyzed, and simulation results confirm the validity of the proposed method.
