Abstract: The background of the remote sensing image is complex,the ships in remote sensing image are similar to the harbor background.Additionally,small and densely arranged ship objects pose challenges for existing deep learning detection algorithms,leading to issues like missed detection,incorrectdetection,and poor accuracy.This paper proposes an improved PPYOLOE-R object detection algorithm for ships in remote sensing images.In this paper,PPYOLOE-R is used as the baseline,and a shuffle attention is introduced in the neck network to enhance the feature extraction capability of the model.This paper introduces an improved Focal Loss,which can combines the category score with the localization score,softens the category labels,and improves the ability to distinguish between difficult and easy samples of model.The ship categoryin the DOTA dataset is extracted to produce the DOTA_ships dataset.Experimental results on the HRSC2016 dataset and DOTA_ships dataset show that the proposed method achieves an average precision of 90.02% and 89.90%,detection speeds of 48.2FPS and 41.5FPS,and recalls of 97.9% and 97.3%,respectively.The average precision and recall are optimal among the compared methods,and the detection speed is second to the PPYOLOE-R.

Key words: Remote sensing image, Ships detection, PPYOLOE-R, Shuffle attention, Focal Loss
