首先分析了基于非相干信号子空间(ISM)的宽带源DOA估计方法，并将基于数 据阵共轭重构的修正MUSIC算法应用于ISM方法中，提高了分辨能力而且可以分 辨相干信源。接下来讨论了相干信号子空间(CSM)方法的宽带相干源DOA估计， 分析了聚焦矩阵及聚焦频率对DOA估计性能的影响，给出了最佳聚焦矩阵的选择 标准和最佳聚焦频率的选择方法。 针对色噪声环境下宽带信号的波达方向估计，研究了将传播算子思想应用于 TCT聚焦矩阵的相干信源DOA估计新方法。该方法基于传播算子思想，直接利用 阵列接收信号估计噪声相关矩阵，得到一种快速TCT聚焦矩阵。从而提高了色噪声 环境下宽带信号DOA估计的性能，传播算子的应用避免了TCT算法中复杂的特征 分解，降低了运算量。通过计算机仿真证明了新方法的有效性和可行性。 关键词： 宽带阵列信号 波达方向估计 色噪声 信号子空间 聚焦矩阵(DOA MUSIC)

附录MATLAB 图像处理命令 1．applylut 功能： 在二进制图像中利用lookup 表进行边沿操作。 语法： A = applylut(BW,lut) 举例 lut = makelut( sum(x(:)) == 4 ,2) BW1 = imread( text.tif ) BW2 = applylut(BW1,lut) imshow(BW1) figure, imshow(BW2) 相关命令： makelut 2．bestblk 功 举例(Appendix MATLAB image processing an order. Applylut functions : the binary image using lookup tables for 2500 operations. Grammar : A = applylut (BW, lut) For lut makelut = (sum (x (:)) == 4. 2) = imread BW1 (text.tif) BW2 = applylut (BW1. lut) imshow (BW1) figure, imshow (BW2) related orders : makelut 2. For bestblk Gong)

Detecting faces or in general, objects, inside gray-level images is still a hard topic for new researches and students all over the world. It s certainly not your fault. Many researches who do not have access to the right resources, struggle for weeks and months before they understand how to manage their project.
