LLS-LFMCWR 2025 No.1
Chief Editors of the Data: Xiaolong Chen Jian Guan
Unmanned aerial vehicles (UAVs) and other "low, slow, and small" (LSS) targets are characterized by low flight altitude, slow movement, and small physical dimensions. These features result in low observability, posing significant challenges to traditional radar detection technologies, especially in complex environments where real-time detection and classification are required. To support research needs, the release of the LSS detection dataset aims to provide high-quality and diverse data for the development of radar target detection and recognition algorithms. This initiative is intended to advance relevant technologies and engineering applications, ultimately enhancing radar systems' capabilities in detecting and identifying LSS targets.
LSS-FMCWR-2.0: Multi-Band and Multi-Angle FMCW Radar Dataset for Low-Slow-Small Target Detection
Chief Editors of the Data: Xiaolong Chen Jian Guan Wang Yuan
The LSS-FMCWR-2.0 dataset contains radar echo data for six types of low-slow-small (LSS) aerial targets: DJI M350 (01), DJI Inspire 2 (02), DJI Mavic 2 (03), a six-rotor UAV (04), a simulated bird (07), and the AC311 helicopter (08). These targets exhibit diverse characteristics in terms of size, structure, and motion, offering a comprehensive representation of the variability found among LSS targets. Data collection was conducted using two frequency-modulated continuous wave (FMCW) radars operating at different frequency bands—K-band and L-band. The K-band radar captured data from multiple angles, and the angular separation between the two radars was set to 0°, 60°, 90°, 120°, and 180°, enabling the capture of rich, multi-dimensional features of the targets. The dataset includes 20 samples each for the DJI M350, six-rotor UAV, DJI Inspire 2, and DJI Mavic 2; 2 samples for the AC311 helicopter; and 4 samples for the simulated bird. With its diversity in target types, complex scenarios, and support for multiple tasks, this dataset serves as a valuable resource for advancing research in radar-based target detection, classification, and recognition of LSS targets.
