| 摘 要： | 论文提出一种基于空间角稀疏表示的2维DOA估计方法,解决了2维DOA估计中冗余字典构造的难题.构建的空间角包含了方位角和俯仰角的信息,利用其构造冗余字典可以将方位角和俯仰角的组合从2维空间映射到1维空间,极大地降低了字典的长度和求解的复杂度；同时将算法推广到频域,扩展了其应用范围.与传统的高分辨算法相比,该方法对信噪比...

| Abstract: | To solve the problem of estimating two dimensional Direction Of Arrival(DOA) using sparse representation,a novel DOA estimation method is proposed to estimate the DOAs of two-dimensional signals based on sparse representation of space angle.So the space angle is put forward to construct the dictionary.By this way,the dimension of dictionary is reduced to one-dimension from two-dimensional space,and the length of the redundant dictionary is largely reduced.Then the algorithm is extended to frequency domain,a... |
