相干分布 meaning in English
coherent distribution
Examples
- 5 ) based on the noise model with a centro - hermitian covariance matrix , a differential denoising bearing estimator is developed for coherently distributed sources in unknown noise fields . its accuracy and resolution performance is analyzed theoretically and numerically
5 )针对未知噪声环境中相干分布源的方向估计问题，提出了一种差分去噪估计器，并从理论和数值结果两个方面评价了它的精度和分辨率性能。 - 2 ) the concept of space frequency distribution is introduced into reevaluation of incoherently distributed source model . based on the model , two low - complexity robust bearing estimators are developed . it is proved theoretically that their estimates are asymptotically unbiased and consistent
2 )从空间频率分布的角度重新评价了非相干分布源模型，提出了两种低计算复杂度的稳健的分布源波达方向估计器，并从理论上证明了它们的渐近无偏性和渐近一致性。 - 3 ) < wp = 12 > using perturbation analysis , the space - correlation loss and the bearing - estimated error for finite - bandwidth incoherently distributed sources are evaluated analytically , respectively . it is disclosed that bandwidth - induced bearing bias increases monotonously with the signal ' s relative bandwidth . when the relative bandwidth is not small enough to be negligible , the spatially - only processing cannot lead to accurate bearing estimate , that is , the joint space and time processing is necessary for high - precision bearing estimation
3 )利用扰动分析方法，解析评价了有限带宽引起的非相干分布源的空间损耗及其对波达方向估计的影响；分析表明，带宽扰动引起的方向估计偏差随信号相对带宽单调增加；当相对带宽无法忽略时，为了得到高精度的波达方向估计，需要进行联合空时处理。
