RFI Detection Dataset

Synthetic Aperture Radar (SAR) dataset for radio-frequency interference (RFI) detection, developed as part of the OpenSAR Insight project. See the organization card for full project background, funding, and consortium details.

Codebase: https://github.com/ESA-PhiLab/OpenSARInsight
Project page: https://opensarinsightweb.web.uah.es/rfi_detection.html
Companion model: opensar-insight/rfi-detection-model

Overview

This dataset uses SAR images from the ESA Copernicus Sentinel-1 mission (Sentinel-1A and Sentinel-1B), which operate in all weather conditions, day and night. The selected Level 1 SAR products are Ground Range Detected (GRD) in wide interferometric mode (IW) and Single Look Complex (SLC) burst products. As with the other OpenSAR Insight datasets, Level 0 (L0, RAW) data extracted from the Level 1 products is included.

The dataset covers 21 SAR scenes, selected using RFI maps and classifications derived from C-band Sentinel-1 measurements provided by Aresys. Data is generated per Sentinel-1 orbit cycle (a 12-day repeat period) and spans June 2019 to September 2023.

Because SLC images are organised by bursts, the patch-generation approach differs from the vessel and flood datasets: square patches are formed considering the start and end of each burst within a band, resulting in patches in the 1400x1400 to 1600x1600 range (which can be pooled or resized as needed for a given model's input size). Patches are identified by patch number, product type, and polarisation. Labels are provided in XML format.

Dataset organisation

The dataset is split into training, validation, and test folders. For each patch:

512x512 VV and VH L1 SLC patches under /patches
Corresponding VV and VH L1 GRD patches under /patches
Corresponding VV and VH L0 patches under /raw
Corresponding VV and VH L0 range-compressed patches under /range_compressed_rescaled
XML file with patch/scene information under /labels/xml_labelling
Binary RFI masks under /labels/binary_masks
