18762 为降低现有的共心式矢量传感器阵列天线间存在的严重互耦影响，进一步提高参数估计精度，该文提出一种稀疏拉伸式L型极化敏感阵列(SSL-PSA)，并针对该阵列提出一种2维波达方向(DOA)和极化参数联合估计算法。 In order to reduce the serious mutual coupling effect across the elements of the existing collocatedvector sensor array and further improve the parameter estimation accuracy, a Sparsely Stretched L-shapedPolarization Sensitive Array (SSL-PSA) is proposed, and a novel method for estimating the azimuth-elevationangles as well as polarization parameters is presented accordingly.
18763 首先建立稀疏拉伸式极化敏感阵列的信号模型，然后将阵列划分为6个子阵，采用子空间旋转不变算法(ESPRIT)算法得到多个旋转不变因子(RIFs)，再根据旋转不变因子间的关系，通过数学运算，得到一组方向余弦有模糊精估计值和4组无模糊粗估计值； Firstly, the signal model of SSL-PSA is established. Then, the SSL-PSA is divided into 6 subarrays, thus the ESPRIT algorithm can be utilized to estimate the Rotational Invariant Factors (RIFs). On this basis, a set of fine but ambiguous estimates and four sets of unambiguous coarse estimates of direction cosine are obtained by a series of mathematical operations.
