Abstract :
In this paper, we consider bandwidth fusion to improve the range resolution. We propose a method based on spectral estimation and amplitude-phase error model to compensate for the lack of mutual coherent between radar subbands. Then we consider two-dimensional fusion to improve the range and cross-range resolution. A new algorithm, called EMEMP, is developed to resolve the poles mismatch occurred in traditional fusion method based on modified Root-Music. By simulations, good performance of these methods will be show.
