This code accompanies the paper titled "An End-to-End Modular Framework for Radar Signal Processing: A Simulation-Based Tutorial," published in IEEE Aerospace and Electronics Systems Magazine (DOI:10.1109/MAES.2023.3334689). The simulation of a complete radar has been performed, and the results have been shown after each stage/module of a radar, enabling the reader to appreciate the impact of the specific process on the radar signal.
