Abstract

This paper presents a direction of arrival (DOA) estimation method using compressive sensing. The CS model is based on the generalized scattering matrix (GSM), presenting antenna characteristics in a spherical mode analysis including mutual coupling between antennas. As a result, the induced currents on antennas by incident waves can be obtained exactly and an accurate solution can be derived. An example is given with 1×6 uniform linear dipole array antenna. In addition, the output is compared with that of the MUSIC algorithm which is a popular method of DOA estimation.
