一种基于统计分析的解定位模糊方法

针对相位测量定位系统是否正确解辐射源位置模糊的判别问题，提出了基于相位差拟合误差均值与方差假设检验的统计判断方法，以逐步剔除错误解；对于剩余的正确辐射源位置估计，给出了提高定位精度的统计处理方法和辐射源位置估计的置信椭圆。仿真试验结果表明，提出的解模糊方法能有效降低将错误解判别为正确解的误判比例，定位结果的统计处理方法可以提升定位精度并缩小置信椭圆。所提方法对于促进相位干涉仪系统的实际应用具有积极意义。

An ambiguity resolution method for emitter localization based on statistical analysis

A statistical analysis method of resolving ambiguity for emitter localization based on phase difference is put forward to eliminate false estimations step-by-step,using hypothesis testing of mean and variance of the fitting error of phase difference. Furthermore,for the residual correct estimation,a statistical method for localization accuracy improvement and the confidence ellipse are given. The results of the simulation experiment not only show that the proposed ambiguity resolution method can effectively reduce the probability of misjudging the false solution as the right solution but also verify that the statistical processing method can improve localization accuracy and reduce error ellipse.The proposed method can hopefully advance the practical application of phase interferometer systems.
