• 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 ) 。

  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。
• The wsf method and ml method can be used in direction finding of coherent sources . we find that tam has the widest direction finding range while the available direction finding ranges of the dsam , sam _ isp , sam _ aisp , sam _ gsp and sam _ agsp are in a certain area centered at the look direction . the sam _ isp , sam _ aisp , sam _ gsp and sam _ agsp can change the effective direction finding ranges by adjusting their inner parameters and furthermore they can improve the sidelobe suppression effect compared with the dsam method
  得到tam的测向范围最宽,基于后五种简化阵列流形的测向方法其测向有效范围均是集中在波束指向附近的一定范围内,其中sam _ isp 、 sam _ aisp 、 sam _ gsp和sam _ agsp对应的测向范围可通过调整内部的参数进行相应的调整,相应地较dsam也可改善对旁瓣源的抑制效果。
