A Curvature-Based Fast Back-Projection Method for Ice-Sounding Radar Imaging
Synthetic aperture processing of radar sounding in ice is made complicated by the curvature of the ice surface. In order to tackle this issue, this study presents a fast back-projection (FBP) ice exploration imaging method based on the ice-surface curvature, aimed at reducing its effect on the ice-sounding radar imaging results. The specific implementation steps of the proposed method are applied in the simulation of point targets and ice-sounding radar data. Experiments verify the effectiveness of the proposed algorithm in ice sheet imaging. The experimental results demonstrate that the algorithm can enhance imaging quality (increase the signal-to-noise ratio (SNR) by approximately 15–20 dB) while only slightly increasing time complexity.
