摘要
在现代战争中,利用无人机集群对敌方组网雷达进行欺骗干扰作为一种有效对抗手段受到了广泛应用.然而,面对复杂作战环境,无人机集群搭载的数字存储转发设备因其精度受限而存在转发时延误差,这将导致实际生成的虚假目标点和预设虚假目标点产生偏移,使欺骗效果大打折扣.针对此问题,本文在组网雷达站址及其射频辐射参数等信息先验已知的情况下,基于"同源检验"思想,在组网雷达空间分辨率一定时,分析了数字存储转发技术对组网雷达进行有效欺骗干扰的边界条件,并针对典型组网雷达系统,探明了转发延迟误差与欺骗干扰效果的影响规律.仿真结果表明,分析和推导的结果能够对实际干扰机性能可否对组网雷达实施有效欺骗干扰给出可行性判定.
Abstract
In modern warfare,the use of UAV swarm to deceive and interfere with the hostile networked radar has been widely used as an effective countermeasure.However,when facing a complex combat environment,the digital storage and forwarding equipment carried by the UAV swarm has forwarding delay error due to its limited accuracy.This delay error will lead to a deviation between the generated false target point and the preset false target point to re-duce the effectiveness of deception significantly.To address this issue,in given prior knowledge of the location and RF radiation parameters of networked radar stations,this paper proposes a solution based on the concept of"homologous test"and the certain spatial resolution of networked radar.The boundary conditions for effective deception jamming by digital storage and forwarding technology to networked radar are analyzed,and the influence of forwarding delay error on deception jamming effect in typical networked radar systems is identified.Simulation results demonstrate that the analy-sis and deduction results can provide a reliable assessment of whether the actual jammer performance can effectively de-ceive and interfere with the networked radar.
