MATLAB Radar Echo Signals and Window Functions Analysis

This article provides an in-depth exploration of MATLAB radar echo signal processing. We examine different types of echo signals, including scattered echoes and reflected echoes, while explaining their practical applications in radar systems. For signal generation and processing, MATLAB implementations typically involve pulse compression techniques and matched filtering algorithms to enhance signal-to-noise ratio. Additionally, we comprehensively cover the concepts and applications of various window functions such as rectangular window, Hanning window, and Blackman window. Each window function can be implemented using MATLAB's built-in functions (e.g., rectwin, hann, blackman) with specific parameter configurations to control spectral leakage and resolution trade-offs. By understanding the characteristics of these window functions through practical code examples, readers can better comprehend their roles and advantages in signal processing applications. Through detailed algorithm explanations and implementation considerations, this article aims to provide readers with comprehensive knowledge of MATLAB radar echo signals and window function applications.
