DOA estimation is very important in array signal processing, while traditional algorithms such as Multiple Signal Classification algorithm(MUSIC) requires eigenvalue decomposition of covariance matrix and spatial spectral peak in the whole search, which is difficult and time-consuming. In particular, there exists robustness problem in two-dimensional DOA estimation algorithm. This paper presents a DOA estimation algorithm based on minimum cross-entropy spectral analysis, which requires only one array of sam...
