Focused Compressive Sensing for Underdetermined Wideband DOA Estimation Exploiting High-Order Difference Coarrays


Group-sparsity-based method is applied to the <inline-formula><tex-math notation="LaTeX">$2q$</tex-math> </inline-formula>th-order difference coarray for underdetermined wideband direction of arrival (DOA) estimation. For complexity reduction, a focused compressive-sensing-based approach is proposed, without sacrificing its performance. Different from the… (More)
