摘要: 有源轉(zhuǎn)發(fā)式干擾成為防空反導(dǎo)、反艦攻擊等典型作戰(zhàn)場景下非常重要的一種干擾樣式，對現(xiàn)代雷達(dá)形成了嚴(yán)重威脅。該文針對有源轉(zhuǎn)發(fā)式干擾對雷達(dá)形成的距離欺騙性假目標(biāo)干擾和角度欺騙性干擾兩種典型情況，研究了全極化單脈沖雷達(dá)識別轉(zhuǎn)發(fā)式干擾并加以抑制的方法，理論推導(dǎo)和仿真實(shí)驗(yàn)結(jié)果表明利用極化信息可以識別并抑制此類干擾，這對新一代極化雷達(dá)適應(yīng)復(fù)雜電磁環(huán)境問題的研究具有深刻的理論指導(dǎo)和借鑒意義。

Abstract: The active repeater jamming is a very important jamming technique in the modern warfare, especially for the air defense, anti-missile and anti-warship operations. It becomes a serious threat for the modern radar systems. This paper focuses on the representative distance-deception and angle-deception artifacts in radar formed by the active repeater jamming techniques. The discrimination and suppression of such active repeater jamming with fully polarimetric mono-pulse radar is studied. The theoretical investigations and simulation experiments demonstrate and validate that the utilization of polarization information has the capability to identify and suppress these jamming patterns. The obtained conclusion shows great potential for the further studies and can assist the investigation of the issue that how radar can be adapted to the complex electromagnetic environment.-
