【摘要】：作為一種重要的欺騙干擾樣式,轉(zhuǎn)發(fā)式干擾通過對雷達(dá)發(fā)射信號存儲轉(zhuǎn)發(fā),形成的距離欺騙假目標(biāo)在空間上是分散的。而分布式多站雷達(dá)進(jìn)行空間配準(zhǔn)時(shí),會將未分布于一個(gè)空間分辨單元內(nèi)的假目標(biāo)剔除,使之失去干擾效果。因此,有必要研究轉(zhuǎn)發(fā)式干擾對分布式多站雷達(dá)的干擾能力。該文在多站雷達(dá)中各雷達(dá)站相距不遠(yuǎn)的條件下,從空間分辨單元的物理含義入手,導(dǎo)出了多站雷達(dá)在一定空間分辨率下,轉(zhuǎn)發(fā)式干擾能對其進(jìn)行有效干擾的條件。當(dāng)干擾機(jī)位于遠(yuǎn)場區(qū)域時(shí),證明了相同時(shí)延產(chǎn)生的假目標(biāo)必然可對多站雷達(dá)實(shí)現(xiàn)有效欺騙;當(dāng)干擾機(jī)位于近場區(qū)域時(shí),推導(dǎo)出有效干擾的欺騙距離范圍,通過控制轉(zhuǎn)發(fā)延遲量,可保證對多站雷達(dá)的欺騙效果。該結(jié)論對多站雷達(dá)的干擾和抗干擾均具有重要的指導(dǎo)意義。
[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.
