| 摘 要： | 为得到多源定位问题的更加精确的解，给出了一个非线性半定规划的内点算法。求解多源定位问题的一般方法都是将参数矩阵的半正定性松弛，而本文在保证该约束条件满足的情况下求解一个半定规划，从而可以得到更加精确的结果。

| Abstract: | Objective: To obtain the more accurate solution of the near - field multiple source localization Methods: An interior point method for nonlinear semidefinite programming was used. Results: The method was effective when the positive semidefinite of parameter matrix was guarante- ed. Conclusion: The result will be more accuarate. |
