Research on delay error of UAV swarm repeater deception against networked radar

In modern warfare, using a UAV swarm as an effective countermeasure to deceive and interfere with hostile networked radar is a common tactic. However, when facing a complex combat environment, the digital storage and forwarding equipment carried by the UAV swarm has limited accuracy, resulting in poor forwarding delay. This delay leads to a deviation between the actual generated false target point and the preset false target point, significantly reducing the effectiveness of deception. To address this issue, this paper proposes a solution based on the concept of "homologous detection" and the certain spatial resolution of networked radar. The boundary conditions for effective deception jamming by digital storage and forwarding technology 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 analysis and deductions can provide a reliable assessment of whether the actual jammer performance can effectively deceive and jam the networked radar.
