A Multi-Frame Super-Resolution Imaging Method for Forward-Looking Scanning Radar

Super resolution technology has played a significant role in enhancing the imaging resolution of forward-looking scanning radar. However, a large number of super-resolution methods still rely on single frame scanning echoes. This paper aims to leverage multi-frame real beam images for super-resolution imaging, utilizing the complementary information present in multiple images to construct a higher resolution image. This paper first establishes the multi-frame super-resolution imaging model. Subsequently, a feasible multi-frame super-resolution method was proposed, and motion parameter estimation was performed using the correlated phase method. Finally, the effectiveness of the proposed method was verified through simulation experiments.
