Unknown mutual coupling effect can degrade the performance of a direction of arrival estimation method. In this letter, a new method is proposed for uniform linear arrays (ULAs) to tackle this problem. Considering the sparse representation exploiting the inherent structure of the received data, the effective block sparse representation and the convex optimization problem are constructed using the steering vector parameterizing method. The proposed solution based on the ${l} _{1}$ - singular… CONTINUE READING
