Method, device and equipment for automatically marking radiation quality problem of SAR (Synthetic Aperture Radar) image

The invention provides an automatic marking method, device and equipment for a radiation quality problem of an SAR (Synthetic Aperture Radar) image. The method comprises the following steps: acquiring a thumbnail of the SAR image; performing azimuth defocusing detection on the thumbnail, and determining an azimuth defocusing degree of the thumbnail based on a detection result; performing gain imbalance detection on the thumbnail, and determining a gain imbalance position in the thumbnail based on a detection result; performing blurring fuzziness detection on the thumbnail, and determining a blurring fuzziness level of the thumbnail based on a detection result; and marking corresponding problems of the thumbnail based on the azimuth defocusing degree, the gain imbalance position and the blurring fuzzy level. According to the automatic marking method for the SAR image radiation quality problem, the radiation quality problem existing in the SAR influence can be quickly and accurately found, and effective marking
