Classic Article on Passive Source Localization and Tracking with MATLAB Implementation

This MATLAB implementation corresponds to the IEEE TRANSACTIONS ON SIGNAL PROCESSING classic paper "An Approximately Efficient TDOA Localization Algorithm in Closed-Form for Locating Multiple Disjoint Sources With Erroneous Sensor Positions." The algorithm achieves joint localization of multiple targets using Time Difference of Arrival (TDOA) information while accounting for erroneous sensor positions. The implementation includes key components such as error compensation mechanisms, closed-form solution calculations, and multi-target tracking modules. This code serves as a practical tool for researchers to understand, validate, and further optimize the proposed algorithm, providing insights into TDOA-based localization techniques under imperfect sensor deployment conditions. The implementation demonstrates efficient matrix operations for solving nonlinear equations and incorporates statistical methods for handling measurement uncertainties.
