Fang Algorithm for 2D Signal Source Localization Using Three Base Stations

The Fang algorithm performs 2D localization of signal sources using three base stations, serving as a fundamental method for passive source localization. This MATLAB-based program simulates the complete localization process of the Fang algorithm, providing implementation insights including time difference of arrival (TDOA) calculations, hyperbolic positioning equations, and least-squares estimation. The simulation demonstrates key functions for coordinate solving and error analysis, offering valuable assistance for researchers in passive localization studies.
