SAR Data Processing Explained | From Level 0 to GRD Product Generation

Welcome to this deep-dive into Synthetic Aperture Radar (SAR) data processing! In this video, we walk you through the complete journey of SAR data—from the raw signal acquisition at Level 0 to the generation of a Level 1 GRD (Ground Range Detected) product that’s ready for analysis.

You'll learn: 🔹 What happens at Level 0 (raw data stage)
🔹 How SAR echoes are focused and calibrated at Level 1 SLC
🔹 The steps to generate radiometrically calibrated GRD products
🔹 Key concepts like range/azimuth compression, motion compensation, multi-looking, and geocoding
🔹 How radiometric calibration and terrain correction work

🎓 Whether you're a remote sensing enthusiast, student, or a professional working with SAR datasets like Sentinel-1, NISAR, or RADARSAT, this video gives you a clear conceptual and practical understanding of the SAR data pipeline.
