Under the situation of minimum-redundancy array (MRA), snapshot will impact on the estimation performance of the direction of arrival (DOA). In respect of Toeplitz multiple signal classification (MUSIC) algorithm’s principle, this paper has analyzed the correlation coefficient to the Toeplitz MUSIC algorithm influence, and through deducing the relation between snapshot and correlation coefficient,...
The algorithm of joint polarization-DOA estimation is presented in this article based on polarization sensitive circle array. This algorithm realizes polarization and DOA joint estimation by MUSIC, avoiding restriction to the array structure and parameter association of the ESPRIT. At the same time circle array assures the array's effective aperture is invariant at the all directions, moreover comparing...
