"PAUD-Passive Acoustic UAV Dataset"

" Passive Acoustic UAV Dataset (PAUD)[](https:\/\/creativecommons.org\/licenses\/by-nc\/4.0\/)[](#dataset-specifications)\ud83d\udcd6 OverviewThis repository hosts a comprehensive **Passive Acoustic UAV Dataset**, captured using a high-density **208-channel microphone array** complemented by reference optical recordings.The dataset is designed to advance research in passive sensing, covering diverse environments including **controlled anechoic chambers** and **challenging outdoor scenarios** (daytime, nighttime, and long-range flights). It provides a robust foundation for tasks such as UAV detection, localization, tracking, beamforming, and multimodal learning. \u26a0\ufe0f Important Usage Notes1.  **Primary Source:** The 208-channel acoustic recordings are the ground truth for quantitative experiments.2.  **Synchronization:** While camera data provides visual context, it is **not** hardware-synchronized.    * *Note:* In `Test7` and `Test8`, a temporal offset exists between audio and video. Users must perform manual temporal alignment before joint acoustic-visual analysis.3.  **Preprocessing:** Depending on your application, you may need to perform task-specific preprocessing such as channel mapping, segmentation, or coordinate calibration. "
