Performance Research on Anti-noise AM Spot Jamming of PRBC-SFM Combined Fuze
This paper gives the research on the anti-noise AM spot jamming performance of pseudo-random binary code phase modulation and sine FM combined fuze based on the criterion of signal to jamming ratio gain.First,the overall signal to jamming ratio gain of its receiver is reduced in detail under the noise AM spot jamming,then,the factors affecting anti-jamming performance are analyzed.The results show that the PRBC-SFM combined fuze has stronger performance of anti-noise AM spot jamming,and its anti-jamming performance can be improved effectively by choosing the parameters of the n-th order Bessel function,and along with decreasing periods and narrowing code width,Doppler frequencys influence on the anti-noise AM spot jamming performance of the PRBC-SFM combined fuze is debased.
