 | 🌐 Level | 🔤 Abbrev. | 📝 Description | 🎯 Purpose / Value |
 |----------|-----------|----------------|--------------------|
-| 📡 **Raw** | – | Unprocessed radar echoes as recorded by Sentinel-1 | Baseline data; allows full custom SAR processing |
-| 🎚️ **Range Compressed** | RC | Echoes compressed in the range dimension via matched filtering | Improves SNR; isolates scatterers along range |
-| 🎯 **Range Cell Migration Corrected** | RCMC | Motion-compensated echoes with corrected range migration | Preserves geometric fidelity; enables proper azimuth focusing |
-| 🖼️ **Azimuth Compressed** | – | Fully focused SAR image in slant-range geometry | Standard **Level-1 product**; interpretable imagery |
