The infrared ship fine-grained categorization technology has wide applications in both civil and military fields. In order to improve the fine-grained categorization accuracy of infrared ships, this paper integrates the channel attention mechanism to design a SE-Resnet module. We use it as the backbone fed into the destruction and construction learning(DCL) framework, which has been proved as one of the most effective fine-grained categorization methods for infrared small object recognition. The experimental results show that our module helps DCL locate key sub-regions, and can further improve the accuracy of fine-grained categorization for infrared ship targets.
