【摘要】：針對(duì)傳統(tǒng)壓制干擾進(jìn)入線性調(diào)頻雷達(dá)無法獲得脈壓增益,在功率有限的條件下干擾效果會(huì)大幅下降和現(xiàn)有干擾方法應(yīng)用范圍較小的問題,提出了基于方波卷積調(diào)制的靈巧干擾方法。該方法在已有卷積調(diào)制干擾的基礎(chǔ)上進(jìn)行設(shè)計(jì)以獲得較好的干擾性能,建立了基于時(shí)域卷積調(diào)制的靈巧干擾數(shù)學(xué)模型,提出了周期方波卷積干擾信號(hào)形式,分析了時(shí)頻特性和干擾效果并進(jìn)行了仿真實(shí)驗(yàn)。仿真結(jié)果表明,通過控制周期方波的各項(xiàng)參數(shù)可以達(dá)到欺騙和遮蓋兩種不同的干擾效果。
[Abstract]:In view of the problem that the traditional suppression jamming can not obtain pulse compression gain in LFM radar, the jamming effect will be greatly reduced under the condition of limited power, and the existing jamming methods will have a small range of applications. A smart interference method based on square wave convolution modulation is proposed. This method is designed on the basis of the existing convolution modulation interference to obtain better interference performance. The mathematical model of dexterous interference based on time domain convolution modulation is established, and the periodic square wave convolution interference signal form is proposed. The time-frequency characteristic and interference effect are analyzed and simulated. The simulation results show that two different interference effects can be achieved by controlling the parameters of periodic square wave.
