Abstract
The invention discloses an iceberg detection method for a South Pole sea area synthetic aperture radar image, and the method comprises the following steps: obtaining the data of the South Pole sea area SAR image, screening a Level-1 SLC product with the latitude of 40-90 degrees S, the data mode being Wave Mode, and the polarization mode comprising HH and VV; the SAR image is manually marked, visual interpretation is performed in combination with geographical location information, shape and texture features, and a South Pole iceberg mark data set in a COCO format is generated; constructing a cascaded convolutional neural network model IB-Detector (IB-Detector); evaluating model performance by using the test set, and outputting iceberg position, contour and area information; according to the method, the iceberg detection precision in a complex scene is improved, and the task requirement of iceberg target detection is met.
