A Robust Clutter Suppression Method for Airborne Radar with Conformal Antennas Array
摘要
Abstract
A novel robust space-time adaptive processing (STAP) method is proposed to eliminate clutter in airborne radar with conformal antennas array. This method filters the target information of range cell under test based on the phase characteristic of target. Then the clutter characteristic are described by constructing AR model and the subspace, which is orthogonal to the clutter and jamming space, is obtained to eliminate clutter. Compared with conventional Doppler compensation methods, direct data domain methods and parametric methods,the proposed method is more robust because its performance can't be influenced by radar working mode and outliers,and it can be applied for arbitrary array.The simulation results demonsttrate its effectiveness.关键词
