【摘要】：針對國內(nèi)外研究關(guān)于連續(xù)波多普勒引信的干擾有效性只作了大量的定性描述,幾乎沒有合適的量化表征參量的問題,提出了以處理增益為表征參量的分析方法,得到了連續(xù)波多普勒引信干擾波形的參數(shù)選擇依據(jù)。該方法理論推導(dǎo)了射頻噪聲干擾、噪聲調(diào)幅干擾、噪聲調(diào)頻干擾、正弦波調(diào)幅干擾、正弦波調(diào)頻干擾、三角波調(diào)幅干擾和三角波調(diào)頻干擾作用下連續(xù)波多普勒引信的處理增益,并進(jìn)行了仿真驗(yàn)證。定量分析和仿真結(jié)果表明:針對連續(xù)波多普勒引信來說,調(diào)幅類干擾信號干擾效能明顯優(yōu)于調(diào)頻類干擾信號,干擾信號的調(diào)制頻率要盡量與引信多普勒頻率一致。
[Abstract]:In order to solve the problem that the interference effectiveness of continuous wave Doppler fuze is only described qualitatively at home and abroad, and there is almost no suitable quantization parameter, an analytical method based on processing gain is proposed. The parameter selection basis of continuous wave Doppler fuze interference waveform is obtained. The theory of this method deduces RF noise interference, noise amplitude modulation interference, noise frequency modulation interference, sine wave amplitude modulation interference, sine wave frequency modulation interference. The processing gain of continuous wave Doppler fuze under the action of triangle-wave AM jamming and triangular-wave FM jamming is verified by simulation. The quantitative analysis and simulation results show that: for CW Doppler fuze. The jamming efficiency of AM jamming signal is obviously better than that of FM jamming signal, and the modulation frequency of jamming signal should be consistent with that of fuze Doppler frequency as far as possible.
