Abstract

In this paper, we study the problem of estimating the target scene via a signal sparse representation (SSR) scheme in the range-Doppler domain. As compared to a range-gate by range-gate SSR analysis, this bidimensional approach can take into account targets straddling two range-gates. Here, we propose a robust SSR Bayesian algorithm that considers the well known grid mismatch problem in both the range and Doppler dimensions. Our algorithm implements a bidimensional approach to a previous described algorithm. Numerical simulations are performed with synthetic and experimental data to demonstrate the benefit of estimating the grid mismatch with the proposed technique.
