Abstract: In this paper, the problem of joint time-of-arrival and two-dimensional direction-of-arrival (TOA/2D-DOA) estimation is solved using space-frequency nested array (SFNA) motion. SFNA is ...

Abstract: Ground-based two-dimensional (2D) array radar suffers from low angular resolution, including azimuth and pitch directions because of the limited size of antenna aperture. In this paper, to ...
