Abstract

In this paper, a DOA estimation method for wideband signals based on sparse representation in FRFT domain is proposed. This method establishes the DOA estimation model and the array popular matrix in the FRFT domain and reconstruct the spatial spectral function based on the sparse representation of the spatial angle, so as to realize DOA estimation of the wideband LFM signals. The algorithm is not only suitable for non-coherent signals, but also can process coherent signals directly without any decoherent operations. Simulation results show that the proposed method can achieve higher estimation performance than the traditional methods, especially at low SNR.
