Construction Of Jamming Signal And Analysis Of Jamming Efficiency To Radio Fuze

In modern war,electronic warfare occupies a very important position,and can even directly affect the outcome of the whole war.Radio fuze is the final link of various artillery and missile warheads in the war,facing increasingly complex jamming,in the electronic countermeasure,at the forefront of the position.In this paper,we study the construction of a radio fuze jamming signal and the interference efficiency of the analysis,summarizes the related theory about building radio fuze jamming signal,from continuous wave doppler fuze,the pseudo-random code phase modulation and pseudo code phase-modulated composite pulse doppler fuze of the three typical radio fuze,this paper analyzes its working principle,as well as the related interference mechanism of fuze,Then different interference waveforms are selected to analyze their action process on the relevant fuze.Through Simulink modeling and simulation of the related fuze,the effect of different interference waveform on the fuze is analyzed.The simulation results show that,as the most common and earliest fuze system,the sinusoidal amplitude modulation aiming jamming with increment modulation can play a good deceptive jamming effect,and the noise amplitude modulation jamming can play a good suppressing jamming effect.For pseudo code phase-modulated fuze,noise amplitude modulated jamming can be used as the basic suppression jamming,and the noise product jamming in smart jamming has not only suppression jamming effect,but also deceptive jamming effect,and different effects can be achieved by adjusting different parameters.For the pseudo-code phase-modulated pulse Doppler composite fuze,this paper analyzes the effects of noise amplitude modulated jamming as the basic suppression jamming,and the effects of double-frequency sinusoidal amplitude modulated jamming,which is a fixed false target deceptive jamming,and explores the effects of the new jamming waveform on the fuze.
