摘要
交替投影(AP)的极大似然算法由于其最接近CR下界的良好似然估计性能和适当的计算量受到人们的重视。本文通过采用直角交叉的两个直线阵实现了AP算法的二维拓展,计算量约与两个一维DOA估计计算量相当。
Alternating projection of maximum likelihood algorithm was recognized as an important method of DOA estimation because of its good statistical approximation to CRB and a modest computational complexity. In this paper, this algorithm was extended to 2-D DOA estimation through two spatial cross-linear antenna array. The computational load correspond to two l-D AP algorithm, the 2-D DOA pair was also solved in this method.
