# π RFInject: Synthetic RF Interference Injection for Sentinel-1 SAR L0 Data
|
| 11 |
+
|
| 12 |
+
## π Motivation
|
| 13 |
+
- **Radio Frequency Interference (\gls{RFI})** is a **major source of performance degradation** in modern **Synthetic Aperture Radar (\gls{SAR})** missions.
|
| 14 |
+
- The **Copernicus Sentinel-1 constellation** is significantly affected, with numerous studies reporting its **detrimental impact**.
|
| 15 |
+
- However, the **lack of standardized and reproducible datasets** has so far **limited systematic benchmarking** of RFI detection and mitigation strategies.
|
| 16 |
+
|
| 17 |
+

|
| 18 |
+
|
| 19 |
+
## π οΈ What RFInject Brings
|
| 20 |
+
**RFInject** introduces a **methodology for controlled synthetic RFI injection** into clean Sentinel-1 L0 raw bursts, enabling:
|
| 21 |
+
- β
**Reproducible benchmarking** of mitigation algorithms
|
| 22 |
+
- β
**Realistic simulation** while retaining authentic system properties
|
| 23 |
+
- β
**Full parameter control** over RFI characteristics
|
| 24 |
+
|
| 25 |
+

|
| 26 |
+
|
| 27 |
+
## π Methodology Highlights
|
| 28 |
+
The framework is based on a **parametric signal model**:
|
| 29 |
+
- π― **Synthetic RFI generation** by superimposing **modulated chirp trains** onto authentic Sentinel-1 radar echoes.
|
| 30 |
+
- π§ **Spectral and statistical fidelity** ensured to reflect real operational systems.
|
| 31 |
+
- π **Metadata-rich parameter sets** controlling:
|
| 32 |
+
- π‘ Waveform diversity
|
| 33 |
+
- π Spatial extent
|
| 34 |
+
- β‘ Power scaling
|
| 35 |
+
|
| 36 |
+

|
| 37 |
+
|
| 38 |
+
## π Dataset Features
|
| 39 |
+
- **Clean Sentinel-1 L0 bursts** β contaminated with **controlled synthetic RFI**
|
| 40 |
+
- **Fully reproducible** contamination scenarios
|
| 41 |
+
- **Rich metadata** for systematic testing across **different algorithms** and **experimental setups**
|
| 42 |
+

+
## π― Impact and Applications
|
| 46 |
+
The dataset empowers researchers to:
|
| 47 |
+
- π΅οΈββοΈ **Detect** RFI more reliably
|
| 48 |
+
- π‘οΈ **Mitigate** its impact effectively
|
| 49 |
+
- π€ Develop **learning-based solutions** for robust **RFI-resilient SAR processing pipelines**
