【摘要】：作为一种重要的欺骗干扰样式,转发式干扰通过对雷达发射信号存储转发,形成的距离欺骗假目标在空间上是分散的。而分布式多站雷达进行空间配准时,会将未分布于一个空间分辨单元内的假目标剔除,使之失去干扰效果。因此,有必要研究转发式干扰对分布式多站雷达的干扰能力。该文在多站雷达中各雷达站相距不远的条件下,从空间分辨单元的物理含义入手,导出了多站雷达在一定空间分辨率下,转发式干扰能对其进行有效干扰的条件。当干扰机位于远场区域时,证明了相同时延产生的假目标必然可对多站雷达实现有效欺骗;当干扰机位于近场区域时,推导出有效干扰的欺骗距离范围,通过控制转发延迟量,可保证对多站雷达的欺骗效果。该结论对多站雷达的干扰和抗干扰均具有重要的指导意义。
[Abstract]:As an important spoofing jamming mode, the forwarder jamming is distributed in space by storing and forwarding radar signals. However, when distributed multi-station radar matches time in space, the false targets which are not distributed in a spatial resolution unit will be eliminated and the jamming effect will be lost. Therefore, it is necessary to study the jamming ability of forward jamming to distributed multistation radar. In this paper, under the condition that radar stations in multistation radar are not far away from each other, starting from the physical meaning of spatial resolution unit, the condition that multi-station radar can be jammed effectively by forwarding jamming at a certain spatial resolution is derived. When the jammer is located in the far-field region, it is proved that the false target generated by the same time delay must be able to effectively deceive the multi-station radar, and when the jammer is located in the near-field region, the range of deception distance of the effective jamming is deduced, and the forwarding delay is controlled. The deceptive effect of multi-station radar can be guaranteed. This conclusion has important guiding significance for jamming and anti-jamming of multi-station radar.
