Abstract:

Pseudorandom code phase modulation fuze has become the key point of fuze countermeasure study, because of its strong anti-jamming ability. Smart noise jamming based on noise convolution modulation is proposed to counter this fuze. The mechanism of generating smart noise based on convolution modulation is stated, and the output signals of the pseudo-random code phase modulation fuze is analyzed under the smart noise jamming. It is proved theoretically that the smart noise jamming could form deceptive jamming and blanket jamming effect on the pseudo-random code phase modulation fuze. Simulations demonstrate that the theoretical -analysis- is valid and the smart noise jamming is more efficient than the traditional jamming methods.
