均匀圆阵模式空间下估计信号源方向，信号源为宽带-Under the uniform circular array pattern space is estimated source direction, the signal source for broadband

阵列信号处理 宽带信号子空间拟合 DOA算法 IEEE 文章-array signal processing for wideband coherent subspace fitting

In this paper, we firstly construct a wide-band undersampling array, then present a novel frequency and direction of arrival (DOA) estimation method for a very wide frequency band (2-18GHz). Choosing a set of appropriate sampling frequencies and

基于非相干信号字空间宽带源DOA估计方法，代码可运行(The matlab code is the DOA estimation for wide-band signals by ISM. It works well.)
