摘　　要：论文对舰载防御雷达系统中面临的近程抗干扰问题进行了分析,提出了一种基于波数域二维成像的目标检测识别方法。采用高分辨率二维成像增强网络检测概率,通过YOLOv5s网络提高系统的抗干扰能力。文章对这一设计思路进行了理论分析和仿真验证,证明了算法的有效性。In this paper,the problem of short-range anti-jamming in shipborne defense radar system is analyzed,and a target detection and recognition method based on two-dimensional imaging in wavenumber domain is proposed.The network detection probability is enhanced by high-resolution two-dimensional imaging,and the anti-interference ability of the system is improved by YOLOv5s network.In this paper,the theoretical analysis and simulation verification of this design idea are carried out,and the ef-fectiveness of the algorithm is proved.
