## 📌 Motivation  
- **Radio Frequency Interference (\gls{RFI})** is a **major source of performance degradation** in modern **Synthetic Aperture Radar (\gls{SAR})** missions.  
- The **Copernicus Sentinel-1 constellation** is significantly affected, with numerous studies reporting its **detrimental impact**.  
- However, the **lack of standardized and reproducible datasets** has so far **limited systematic benchmarking** of RFI detection and mitigation strategies.  

---

## 🛠️ What RFInject Brings  
**RFInject** introduces a **methodology for controlled synthetic RFI injection** into clean Sentinel-1 L0 raw bursts, enabling:  
- ✅ **Reproducible benchmarking** of mitigation algorithms  
- ✅ **Realistic simulation** while retaining authentic system properties  
- ✅ **Full parameter control** over RFI characteristics  

---

## 📐 Methodology Highlights  
The framework is based on a **parametric signal model**:  
- 🎯 **Synthetic RFI generation** by superimposing **modulated chirp trains** onto authentic Sentinel-1 radar echoes.  
- 🧠 **Spectral and statistical fidelity** ensured to reflect real operational systems.  
- 📊 **Metadata-rich parameter sets** controlling:  
  - 📡 Waveform diversity  
  - 🌍 Spatial extent  
  - ⚡ Power scaling
