TDOA Source Code Implementation

This article presents the complete source code implementation for TDOA (Time Difference of Arrival) signal processing, comprising seven distinct program files. Due to the passage of time and insufficient documentation of each file's specific purpose, we need to systematically analyze their individual functionalities through careful examination. The research process involves several key steps: First, we should examine any available documentation or header comments to understand the basic structure and purpose of each file. Many TDOA implementations typically include files for signal correlation analysis, time difference calculation, hyperbolic positioning algorithms, and data visualization components. Next, we need to conduct a line-by-line code analysis of each file to identify the core algorithms and functions. Look for key mathematical operations such as cross-correlation calculations, peak detection algorithms for time difference extraction, and nonlinear optimization methods for source localization. The implementation likely uses MATLAB's signal processing toolbox functions and custom hyperbolic positioning equations. Finally, we should execute the files with sample data to test their operational behavior and validate the localization accuracy. This testing phase might require modifying parameters or input formats to ensure proper functionality. Through this comprehensive analysis, we can fully understand each component's role in the TDOA pipeline and verify the system's correct operation for acoustic or RF signal source localization applications.
