摘要: In this paper, we propose the use of a sparse uniform linear array to estimate direction-of-arrival (DOA) more sources than number sensors by exploiting two continuous wave signals whose frequencies satisfy certain co-prime relationship. This extends and filter concept, which was developed in either spectral or spatial domain, joint spatio-spectral thereby achieving high flexibility structure design meet degrees-of-freedom system complexity constraints. The DOA estimation is implemented difference co-array context avoid undersampling, group sparsity based compressive sensing techniques are used determine direction signal arrivals.
