| 摘 要： | 提出了一种新的基于单个矢量水听器的方位频率联合估计方法--波达方向矩阵法.利用矢量水听器的时延数据,构造了两个相同的子阵,通过对波达方向矩阵的特征分解,实现了对目标信号的波达方向估计,并同时得到了目标的频率特征.计算机仿真实验表明,该方法具有较好的估计精度.

| Abstract: | A novel approach of DOA matrix method was proposed to joint frequency and direction of arrival using a single vector hydrophone.By the temporal invariance,two sub-arrays with the same array shape were constructed.By means of DOA matrix,the joint frequency and direction of arrival estimation could be obtained.The Monte-Carlo simulation results show its validity. |
