Digital SAR processing is the process of compressing the raw, blurred echo energy into sharp, highly resolved pixels. The workflow bridges the gap between raw data collection and actionable GIS visualization.
The primary goal of SAR digital processing is to "focus" this dispersed energy back into distinct, high-resolution points. 3. Core Steps in Digital SAR Processing
