Non-Iterative Hyperbolic Equation System Solution with Analytical Expression Resolution

Y.T. Chan's research paper introduces a non-iterative hyperbolic equation system solution with analytical expression resolution. This algorithm not only demonstrates computational efficiency with minimal calculations and fast processing speed, but also achieves high positioning accuracy when TDOA parameter estimation errors follow a Gaussian distribution. Our program implements an enhanced version of Chan's original algorithm through MATLAB coding. By utilizing known TDOA estimation parameters, we enable more accurate signal source position estimation through sophisticated matrix manipulation and least-square optimization techniques. The implementation includes key functions for coordinate transformation and error covariance analysis, making this algorithm particularly significant for interference source localization and passive positioning research. We aim to provide valuable assistance and inspiration for researchers in related fields through this optimized computational approach.
