针对组网雷达的无人机集群转发式欺骗干扰时延误差研究
Research on Delay Error of UAV Swarm Repeater Deception Jamming against Networked Radar
摘要
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.关键词
