它是提高的到达方向（DOA）估计精度的紧迫任务。解决时间差的DOA估计问题是干扰和噪声的敏感性，本文提出了一种新的多个源的DOA基于multiset的典型相关分析估计算法（MCCA）。-It is to improve the direction of arrival (DOA) estimation accuracy urgent task. DOA estimation problem to solve is the time difference between the sensitivity of interference and noise, this paper proposes a new DOA canonical correlation analysis of multiple sources of estimation algorithm multiset (MCCA) based.
