Global Convergence Gauss-Newton Method Applied to Nonlinear Least Square Estimation in Target Location

This paper proposes an iteration algorithm insensitive to initial guess which combines the global convergence strategy with Gauss Newton method. When applied to nonlinear least square estimation in target location, this algorithm can approach the precise guess by iterations even with the noise polluted initial guess. Some formulas are derived in this paper when this global convergene Gauss Newton method is applied in 2D target location in bistaric radar system.
