In radar applications, when a target is in close proximity to a reflectory surface, the received echo signal reaches the radar site via two or more paths, even though there exists only one target in the environment. So, it is often relevant to estimate the directions and the relative delays of each path ray. We present two approaches to jointly estimate these parameters based on a 2D ESPRIT-like algorithm Van der Veen et al., (1998) in wireless communications. Numerical simulations are provided to access the performance of the proposed approaches, which are compared to the Cramer-Rao bound and the MUSIC algorithm combined with spatial smoothing
