摘要
本文提出了一种新的宽带信号二维来波方向(2D-DOA)估计方法。该方法通过对阵列方向矩进行多项式展开来构造聚焦矩阵,它不需要进行角度预估计和信号个数估计。计算机仿真试验证实了方法的有效性。
A nove method of estimation 2D-DOA of wideband signal has been proposed in this paper formed focusing
matrices by expanding the steering matrix of array It does not need preliminary DOA estimates and number of signals detection.
Computer simulation confirms the methods availability.
