| Abstract: | Jamming effect of suppressing noise frequency modulation jamming of pseudo-random code phase modulation fuze was researched.The principle of pseudo-random code phase modulation fuze(PRCPMF)being jammed was analyzed according to the receiver simulation model,the valuation method of suppressing jamming effect were put forward based on the probability of correlator output value excceding comparison threshold level,and factors influencing jamming effect were discussed.The simulation result shown the jamming effect of pseudo-random code phase modulation fuze can be enhanced by these measures,such as adopting narrow-bandwidth spot jamming,increasing jamming to signal ratio of the receiver,reducing the interference bandwidth,and improving targeting carrier frequency degree. |
