摘要：
The problem of non-coherent direction of arrival (DOA) estimation of wideband signals with magnitude-only measurements is studied in this paper. Unlike the traditional coherent DOA estimation methods, where discrete Fourier Transform (DFT) can be applied to sensor measurements in order to formulate the problem into a narrowband form, the non-coherent model processes wideband signals in time domain directly by exploiting the convolutional sparse coding (CSC) framework. As shown by simulations, the proposed solution has the advantage of being robust against frequency independent sensor response errors.
