2D radar implementation

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. The transmitter, antenna, and receiver subsystems have been simulated in MATLAB with a detailed discussion on waveform generation and transmission, receiver side operations such as matched filtering, Doppler processing, moving target indication filtering, and constant false alarm rate detection. Each step of the receiver chain’s signal processing has been discussed, along with its influence on the signal. The implementation is carried out by simulating a generic 2D pulse-Doppler radar. A comprehensive analysis of the waveform generation and its effect on the target detection performance, varying radar cross-section effect on the reflected wave, and path loss during propagation have been demonstrated. It generates the figures in the paper and provides a structured approach for simulating radar signal processing scenarios. The modular framework enables users to explore and implement various radar processing techniques, making it an effective tool for educational and research purposes. The code supports the reproducibility of the results presented in the paper and offers a hands-on experience for those interested in radar systems.

本代码伴随由IEEE航空航天与电子系统杂志（DOI:10.1109/MAES.2023.3334689）发表的论文《端到端模块化雷达信号处理框架：基于模拟的教程》。该论文通过模拟完整的雷达系统，并在雷达的每一阶段/模块之后展示结果，使得读者能够深刻理解特定处理过程对雷达信号的影响。发射器、天线和接收器子系统均已使用MATLAB进行模拟，并对波形生成与传输、接收端操作如匹配滤波、多普勒处理、移动目标指示滤波以及恒定误报率检测等进行了详细的讨论。接收链信号处理的每一步及其对信号的影响均被详细阐述。实现方式是通过模拟一个通用的二维脉冲多普勒雷达。展示了波形生成及其对目标检测性能的影响、反射波上的雷达散射截面变化效应以及传播过程中的路径损耗的综合分析。它生成了论文中的图表，并提供了模拟雷达信号处理场景的结构化方法。模块化框架使用户能够探索和实现各种雷达处理技术，成为教育与研究目的的有效工具。该代码支持论文中呈现结果的复现，并为对雷达系统感兴趣的读者提供了实际操作经验。
