在多基阵纯距离测量条件下，为提高目标定位精度，首先建立了多基纯距离目标定位系统最小二乘估计模型；然后，将全局收敛策略与高斯-牛顿法相结合，得到了解决多基纯距离目标定位问题的基于全局收敛策略的牛顿迭代算法，算法保留了二阶以上的观测误差；最后，对算法进行了仿真实验。仿真实验表明：与线性近似法相比，基于全局收敛策略的牛顿迭代算法提高了定位精度，增强了定位稳定性，有效地改善了多基纯距离目标定位系统的定位性能。

To increase the precision of target location in the multi-station range-only measurement ,a nonlinear least square estimation model is established for the multi-station range-only target location system .Then ,the combination of the convergent method with the Gauss-Newton method leads to the Gauss-New ton iterative algorithm based on Global Convergence ,w hich is used for solving the problem of multi-station range-only target location . T he algorithm retains a second-order observation error . The simulation experiment demonstrates that this method is better in the precision and stabilization of location than the linear approximation method .
