针对组网雷达的自卫式航迹欺骗干扰技术

    Self Defense False Track Simulation Technology for Netted Radar

    • 摘要: 组网雷达通过多源异构信息融合技术不但提升了目标的探测精度,而且提升了雷达的抗干扰能力。文中针对组网雷达的信息融合机理,通过对网内不同体制雷达产生相关假目标,降低组网雷达数据中心对虚假点迹的剔除能力,能够实现在网内不同雷达上形成相关虚假航迹干扰。针对现代反导雷达具备宽带成像能力,能够根据回波的散射特性区分真假目标,文中提出了基于强散射点的宽带假目标模拟技术,通过逼真模拟不同姿态条件下各强散射点的距离和微多普勒频率,结合虚假航迹产生技术,实现了对组网雷达的高逼真航迹欺骗干扰。利用某型导弹的电磁散射数据,在特定照射角度下提取4个强散射点信息,在干扰模拟器中实现了4散射点假目标模拟,并在某宽带雷达上进行了实验验证,效果与仿真结果一致。

       

      Abstract: Netted radar realizes cooperative detection through multi-source information fusion technology, which not only improves the detection accuracy of target, but also greatly improves the anti-jamming ability of radar. Aiming at the information fusion mechanism of netted radar, the ability of netted radar data center to eliminate false track is reduced by generating relevant false target for different radar systems in the network, and the formation of relevant false track interference on different radars in the network can be realized in this paper. In addition, in view of the modern anti-missile radar wideband imaging ability, which can distinguish true and false target according to the properties of scattering echo, a broadband false target simulation technology based on the strong scattering point is proposed in this paper, through realistically simulating the distance and micro-Doppler frequency of the strong scattering point under the condition of different poses, combined with false track technology, realized the high realistic path of netted radar deception jamming. By using the electromagnetic scattering data of a certain missile and the information of four strong scattering points in advance at a specific irradiation angle, the simulation of the false target with four scattering points is realized in the jamming simulator, and the experimental results are verified on a wideband radar.
