源波 meaning in English
wave of source
Examples
- An approach for direction of arrival estimation of distributed sources induced by local scattering
分布式信号源波达方向估计方法 - So far , many methods have been proposed to estimate the nominal bearing of spatially distributed source
迄今为止，已经提出了多种空间分布源波达方向估计方法。 - The application of polymers ( as passive waveguide materials ) to intergrated optical sensing ( evanecent wave sensing ) is a new try as compared with that in thermal sensing [ using thermo - optic ( to ) modulators ] or voltage sensing [ using electro - optic ( eo ) modulators ]
相对于温度传感(热光调制器)和电压传感(电光调制器)应用，将聚合物作为无源波导材料用于集成光波导化学传感(倏逝波相位传感)是个新的尝试。 - 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。 - Also , much related research requires the narrowband assumption , which is not always realistic in practical applications . it is necessary to analyze the effects of finite bandwidth to bearing estimation of spatially distributed source . additionally , more complex noise models should be dealt with in practical situations as well as that of white gaussian noise
不过，其中多数方法仅适用于小角度扩展情况，当角度扩展比较大时，需要在估计的稳健性和运算量之间进行折中；而且，许多方法要求信号传播满足窄带假设，这在实际的应用场合中可能很难得到满足，有必要分析信号带宽对分布源波达方向估计的影响；另外，也有必要考虑空间色噪声环境中的分布源波达方向估计问题。
