OSR_DATASET

This dataset provides electromagnetic spectrum feature data for target recognition in combat formations, supporting both closed and open set scenarios. It includes three subsets: a closed set with known target types, open set 1 with one unknown target type, and open set 2 with multiple unknown target types. Each dataset contains extracted target features, adjacency matrices representing communication links, and ground truth labels. The dataset covers radar and communication attributes, including carrier frequency, pulse characteristics, modulation types, power, and movement parameters. Preprocessing methods such as min-max normalization and label encoding are applied. The adjacency matrix captures target relationships, making the dataset suitable for graph-based learning models. This dataset facilitates research in open set recognition and target classification under real-world conditions of incomplete and unknown target data.
