Compressive sensing in Direction of Arrival (DOA) applications. A comparative study on different acquisition systems
Nowadays, many technologies and algorithms are available for the DOA estimation, aimed at satisfying the both the accuracy requirements and the antenna installation constraints. The authors propose here a comparative study on different choices of antenna systems designed for the DOA estimation, performed with a compressive sensing approach. This work is organized as follows. After a brief introduction on the DOA estimation systems and compressive sensing algorithms, we apply a compressive sensing algorithm to both vector and standard antenna array systems.
