Because of its special antenna structure , testing the antenna ’ s performance is necessary to prove its theory . auto measurement system of cfa array annates can measure the annates ’ s amplitude - phase character and resistance matrix quickly and effectively 舰载超视距雷达使用交叉场天线cfa ( crossedfieldantenna )作为阵列天线阵元,由于其特殊的天线结构,对其特性的理论研究也需要测量数据来验证。
Robustness is the study focus of adaptive beamforming techniques because of the inevitable array imperfections in practice . a robust adaptive beamformer based on the structure of the generalized sidelobe canceller ( gsc ) is proposed in this thesis 由于阵列天线的空间采样误差不可避免，自适应波束形成的稳健性是当前波束形成研究的热点，论文提出了一种基于广义旁瓣相消器结构的稳健的自适应波束形成器。
The covariance of the training samples which are sampled from the antenna arrays is delivered into svm training machine after transformed suitably , then we use svm regression on the unknown samples according as the trained machine for getting the source location 把阵列天线采集的训练样本的协方差矩阵进行适当变换之后送入svm训练器进行学习，然后根据这个学习机对未知样本进行svm的函数拟合，得到信源方向。
Because super - directive arrays can supply better directive performance than the general arrays , we analyses the two pattern synthesizes that is the schelkunoff unit - circle method and the chebyshev - dolph super - directive synthesis method of the line arrays in detail 由于超方向性阵列天线可以提供比普通阵列天线好得多的方向特性。本文尤其对线阵的schelkunoff单位圆综合法和chebyshev - dolph超方向性综合法作了详细的分析。
This dissertation is focused on the study of adaptive digital beam forming ( dbf ) , two - dim spectrum estimation and the determination of the highness of the object . main work include : 1 a method of adaptive dbf in received antenna array 本文围绕着自适应接收波束形成、时-空二维谱估计和对目标高度判定等方面进行研究，主要研究工作包括以下几个方面： 1讨论了在接收阵列天线中，自适应数字波束形成( dbf )的方法，引入了采样梯度矩阵算法。
