摘要:
提出用模糊函数切割法评判伪码调相脉冲多普勒(PD)引信的固有抗干扰性能。该引信模糊图切割面面积的计算结果表明,伪码调相PD引信的固有抗干扰性能随脉冲宽度的增大而线性减弱,固有抗干扰性能及其改善程度与调制的伪码序列长度成正比。通过与PD引信固有抗干扰性能的比较,发现在研究的脉冲宽度(0.8~4.0μs)内,伪码调相PD引信的固有抗干扰性能明显强于前者。研究结果表明,基于模糊函数切割法的无线电引信抗干扰性能测度理论和方法不但能够测度同一体制不同工作参数下引信的固有抗干扰性能,而且能够评判不同体制引信在指定工作参数下的固有抗干扰性能。
Abstract:
The method of ambiguity function incision is proposed to evaluate the inherent anti-jamming capability of pseudorandom code combined with pulse Doppler(Pseudo-noise pulse Doppler(PN-PD)) fuze.The incision areas of the fuse ambiguity diagrams are calculated.The inherent anti-jamming capability of the PN-PD fuze gets weaker with pulse width widening linearly.The inherent anti-jamming capability of PN-PD fuze and its improvement extent are in direct proportion to the modulated m-sequence length.Compared with the inherent anti-jamming performance of the pulse Doppler fuze,it is demonstrated that the inherent anti-jamming capability of PN-PD fuze within the range of 0.8~4.0 μs is remarkably stronger than the former one.The research results show that the evaluation methodology based on the method of ambiguity function incision can not only evaluate the inherent anti-jamming capability of the same type of fuze with different working parameters and of different types of fuzes with specified working parameters.
