阵列流 meaning in English
array stream
Examples
- Applying simplified array manifolds can reduce the array calibration cost , and compared with the tam method , these simplified array manifolds can make the multidimensional

对均匀圆阵列( uca )二维波达方向估计问题，运用相位激励模式波束形成技术，得到圆阵波束空间实值阵列流形。 - Because these methods do not need not only the doa of the signal ' s and the array manifold but also signal waveform , the blind beamforming algorithms using cyclostationarity signal ' s properties are the genuine blind algorithms
该方法既不需要知道来波方向和阵列流形，也不需要提供训练数据，仅利用信号的循环平稳特性就可以实现真正意义上的盲自适应波束形成。 - 2 - d superresolution direction finding methods at subarray level suited for plane phased arrays are studied . for overcoming the limitations of true array manifold ( tam ) that the expense and cost of the array calibration are high and the calibration realization is complex , five kinds of simplified array manifolds are proposed , namely direct simplified array manifold ( dsam ) , simplified array manifold based on ideal subarray patterns ( sam _ isp ) , simplified array manifold based on approximate ideal subarray patterns ( sam _ aisp ) , simplified array manifold based on gaussian subarray patterns ( sam _ gsp ) , simplified array manifold based on approximate gaussian subarray patterns ( sam _ agsp ) respectively . the performances of applying these array manifolds to music , wsf and ml methods at subarray level are analyzed
本文研究了平面相控阵二维子阵级超分辨测向,针对真实阵列流形( tam )校正成本和代价高以及实现复杂的缺陷,提出了五种简化的阵列流形分别为直接简化的阵列流形( dsam ) 、基于理想子阵方向图的简化阵列流形( sam _ isp ) 、基于近似理想子阵方向图的简化阵列流形( sam _ aisp ) 、基于高斯子阵方向图的简化阵列流形( sam _ gsp )和基于近似高斯子阵方向图的简化阵列流形( sam _ agsp ) 。 - Under ideal conditions , adaptive array signal processing methods can get excellent performance and adaptive beamformers provide an improvement in array output signal - to - interference - plus - noise - ratio ( sinr ) in comparison with conventional beamforming . in practical operating circumstances , the performance of adaptive array signal processing methods degrade extremely due to existing errors
但是，在实际系统中总存在有误差，包括自适应训练样本有限次快拍引起的协方差矩阵的估计误差和各种系统误差，误差使得实际阵列流形与理想阵列流形存在差异，这时自适应阵列信号处理的性能会急剧下降。
