MATLAB Simulation of Three Classic Algorithms for Synthetic Aperture Radar Imaging

In this article, I present three classic algorithms for synthetic aperture radar (SAR) imaging: the Range Doppler (RD) Algorithm, Chirp Scaling Algorithm, and wK Algorithm, along with their MATLAB implementations. Each algorithm is correctly implemented with clear, understandable code annotations. Through simulation experiments, we can gain in-depth understanding of these algorithms' principles and performance characteristics. We will discuss each algorithm's processing steps and key concepts in detail, including implementation approaches such as range compression, azimuth compression, and phase compensation techniques. The article analyzes the advantages and limitations of each algorithm, exploring how to select appropriate algorithms based on specific application scenarios and evaluating their performance under different conditions. Additionally, we provide insights for improving and extending these algorithms, suggesting potential modifications to enhance SAR image quality and computational efficiency through techniques like optimized interpolation methods and parallel processing implementations.
