mrzamaniiii/Time-Domain-Back-Projection-Method

The project is a standard implementation of the Time-Domain Back-Projection (TDBP) algorithm, which is a textbook method for SAR image reconstruction. With only 9 stars and minimal activity, it represents a personal research or educational repository rather than a production-grade library. TDBP is computationally expensive compared to frequency-domain methods like Range-Doppler, and while it handles non-ideal flight paths better, this specific implementation offers no novel optimizations or GPU-acceleration (CUDA) that would provide a competitive moat. It is significantly outperformed by established industrial tools like ESA's SNAP (Sentinel Application Platform) or NASA/JPL's ISCE2. Frontier labs are unlikely to compete here as this is a niche aerospace/remote sensing niche, but the project is easily displaced by any graduate-level radar engineering coursework or more mature open-source geospatial toolkits.
