非正侧阵雷达距离模糊杂波抑制新方法
New method for range-ambiguous clutter suppression in non-side-looking airborne radar
摘要
Abstract
To suppress the seriously range-ambiguous clutter, an approach based on the frequency diverse array (FDA) technique is proposed.Based on the space-time signal model in FDA radar, the frequency increment is designed to distinguish the clutter at ambiguous ranges and avoid signal decorrelation.Then, the subspace projection algorithm is used for range-ambiguous clutter suppression.Numerical simulations show the effectiveness of the proposed method.Even when the number of the elevation degrees-of-freedom (DOFs) is limited, the proposed method performs better than the conventional elevation filtering method.关键词
