摘要:
以信干比增益作为衡量标准来研究伪码调相与正弦调频（PRBC-SFM）复合引信抗瞄准式噪声调幅干扰性能。详细推导了存在瞄准式噪声调幅干扰时复合引信接收机的总信干比增益，分析了影响抗瞄准式噪声调幅干扰的因素。结论表明：PRBC-SFM复合引信具有较强的抗噪声调幅干扰性能；合理的选择n阶贝塞尔函数的阶数n和宗数mf，可以有效地提高其抗瞄准式噪声调幅干扰的能力；减小伪码周期和码元宽度，可以降低多普勒频率对复合引信抗瞄准式噪声调幅干扰性能的影响。
Abstract:
The purpose of this paper is to research the anti-noise AM spot jamming performance of pseudo-random binary code phase modulation and sine FM (PRBC-SFM ) combined fuze based on the criterion of signal to jamming ratio(SJR) gain.First,the overall SJR gain of its receiver is reduced in detail under the noise AM spot jamming,then, the factors affecting its anti-jamming performance are analyzed.The results show that the PRBC-SFM combined fuze has stronger performance of anti-noise AM spot jamming,its anti-jamming performance can be improved effectively by choosing the reference of n and mf of the n-th order Bessel function,and along with the decrease in periods of the pseudo code and narrowing of the code element width,the influence of Doppler frequency on the anti-noise AM spot jamming performance of the PRBC-SFM combined fuze is reduced.
