Detailed Documentation

In SAR imaging systems, the RD (Range-Doppler) algorithm represents one of the most classical correction methodologies. This algorithm employs a sophisticated least-squares based approach that effectively mitigates phase noise and ambiguity artifacts in imaging results, thereby significantly enhancing image clarity and geometric accuracy. Through the accompanying code implementation, users can examine key algorithmic components including range compression, azimuth compression, and motion compensation routines. The implementation specifically demonstrates how to handle frequency domain processing using FFT operations and phase correction through complex multiplication techniques. We strongly recommend downloading and studying the provided codebase to gain deeper insights into SAR imaging principles and practical correction algorithm applications, enabling more effective utilization of SAR technology in real-world scenarios.
