Generalized and Symmetric Coprime Planar Array for Direction of Arrival Estimation
IET Radar, Sonar and Navigation, 2022 Degrees of freedom and mutual coupling are two important factors to determine the ability of direction of arrival (DOA) estimation. Although coprime planar array (CPPA) has less mutual coupling than hourglass array (HA) and ladder array (LA), its ...
