摘要

摘要: 目前對(duì)線性調(diào)頻(LFM)脈沖壓縮雷達(dá)轉(zhuǎn)發(fā)欺騙干擾主要通過(guò)移頻調(diào)制轉(zhuǎn)發(fā)和采樣直接轉(zhuǎn)發(fā)實(shí)現(xiàn)，常規(guī)轉(zhuǎn)發(fā)干擾樣式簡(jiǎn)單，干擾信號(hào)規(guī)律性強(qiáng)、復(fù)雜度低。該文提出一種基于間歇采樣的多載波調(diào)制轉(zhuǎn)發(fā)新型干擾樣式。首先引用碼片的概念對(duì)間歇采樣過(guò)程重新建模，在此基礎(chǔ)上，通過(guò)對(duì)當(dāng)前采樣碼片附加不同移頻量，結(jié)合多載波并行調(diào)制體制對(duì)其進(jìn)行串并轉(zhuǎn)換，利用不同次轉(zhuǎn)發(fā)信號(hào)各子載波間的干擾累積，實(shí)現(xiàn)對(duì)LFM脈沖壓縮雷達(dá)的數(shù)量、幅度、空間分布可控的逼真假目標(biāo)干擾。仿真表明該干擾樣式比移頻干擾和直接轉(zhuǎn)發(fā)干擾具有更好的干擾效果。

Abstract: Repeater deception jamming against Linear Frequency Modulated (LFM) pulse-compression radar is realized by frequency-shift repeater and direct repeater jamming so far. Conventional repeater jamming type is simple. Regularity of jamming signal is strong and complexity is low. A new repeater jamming type with multi-carrier modulation based on intermittent sampling is proposed. Firstly, the model of intermittent sampling is rebuilt with the code chip concept. Based on this, lifelike false targets with the quantity, amplitude and space distribution which can be controlled are produced by attaching different frequency-shift component to the present sampling code chip, deserializing signal used multi-carrier parallel modulation system and utilizing the accumulation of different times repeater signal jamming effect among sub-carriers. The simulation results show that the new jamming type has better performance than frequency-shift jamming and direct repeater jamming.
