【摘要】：针对国内外研究关于连续波多普勒引信的干扰有效性只作了大量的定性描述,几乎没有合适的量化表征参量的问题,提出了以处理增益为表征参量的分析方法,得到了连续波多普勒引信干扰波形的参数选择依据。该方法理论推导了射频噪声干扰、噪声调幅干扰、噪声调频干扰、正弦波调幅干扰、正弦波调频干扰、三角波调幅干扰和三角波调频干扰作用下连续波多普勒引信的处理增益,并进行了仿真验证。定量分析和仿真结果表明:针对连续波多普勒引信来说,调幅类干扰信号干扰效能明显优于调频类干扰信号,干扰信号的调制频率要尽量与引信多普勒频率一致。
[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.
