一篇中文博士论文《宽带信号阵列高分辨到达角估计技术研究》，我认为是一篇比较好的关于宽带信号DOA的博士论文。-a chinese disertation "High Resolution Direction of arrival Estimation of Wideband Array Signals",it is a good disertation in the wideband DOA.

宽带OFDM信号模型的建立，用于宽带OFDM信号的DOA估计，已经用于毕业设计-Wideband OFDM signal model, for broadband OFDM signal DOA estimation, has been used for graduation

提出了一种新的宽带DOA估计方法的基础上的时域宽带信号模型，使用人口蒙特卡罗（PMC）的贝叶斯计算方法。-Proposed model-based wideband signals in time domain, a new wideband DOA estimation method based on the use of population Monte Carlo (PMC) Bayesian calculation.
