Detailed Documentation
This repository presents classical Synthetic Aperture Radar (SAR) imaging algorithms, implementing three primary point-target imaging methodologies: Range Doppler Algorithm (RDA), Chirp Scaling Algorithm (CSA), and Range Migration Algorithm (RMA). The RDA algorithm employs frequency-domain processing for range compression and azimuth focusing through Doppler centroid estimation. CSA simplifies range cell migration correction using phase multiplication operations without interpolation, while RMA utilizes precise Stolt interpolation for wavefront reconstruction. These algorithms incorporate key digital signal processing techniques including matched filtering, phase compensation, and Fourier transform operations, enabling high-resolution radar image generation through efficient MATLAB implementations with optimized FFT-based computations.
