【摘要】：無線射頻干擾注入可對(duì)無線通信網(wǎng)絡(luò)系統(tǒng)進(jìn)行干擾,甚至實(shí)現(xiàn)非授權(quán)接入實(shí)施網(wǎng)電攻擊。若捕獲敵方的通信協(xié)議,掌握其采用的通信模式,如何進(jìn)行干擾甚至將虛假的信息注入無線網(wǎng)絡(luò),是實(shí)施網(wǎng)電攻擊的技術(shù)難點(diǎn)。針對(duì)指揮通信系統(tǒng)中的無線開放環(huán)節(jié),基于軟件無線電技術(shù),分析了戰(zhàn)場(chǎng)通信目標(biāo)信號(hào)系統(tǒng)的技術(shù)指標(biāo),對(duì)編碼方式、信號(hào)帶寬、載波頻率、調(diào)制方式和調(diào)制滾降系數(shù)等主要參數(shù)進(jìn)行分析,在MATLAB/Simulink環(huán)境下建立QPSK數(shù)字頻帶傳輸系統(tǒng)和射頻干擾注入系統(tǒng)模型,并且對(duì)關(guān)鍵節(jié)點(diǎn)進(jìn)行仿真。仿真結(jié)果表明,在不同干擾方式下,通信系統(tǒng)會(huì)受到較明顯的干擾,或者解調(diào)出與注入一致的干擾信息,達(dá)到了驗(yàn)證設(shè)計(jì)的目的。
[Abstract]:Radio frequency interference injection can disturb the wireless communication network system, even realize unauthorized access to implement network power attack. If capturing the communication protocol of the enemy, mastering the communication mode, how to interfere and even inject false information into the wireless network, it is the technical difficulty to implement the network power attack. In the wireless open link, based on the software radio technology, the technical indexes of the battlefield communication target signal system are analyzed. The main parameters of the coding mode, signal bandwidth, carrier frequency, modulation mode and modulation roll drop coefficient are analyzed. The QPSK digital frequency band transmission system and the radio frequency interference injection system are built in the MATLAB/Simulink environment. The simulation results show that the communication system will be disturbed obviously in different interference modes, or demodulates the interference information consistent with the injection, and achieves the purpose of verification design.
