Firstly.the working principle of pseudo-random code phase-modulation fuze is described in the paper.In suc- cession,the formula of signals in every aspects and the maximum output peak power SNR in the correlation detection are deduced in the case of jamming of white Gauss noise.Effect of white Gauss noise to the correlation detection of pseudo-random code phase-modulation fuze is studied when different noise input power are input.It is concluded that pseudo-random code phase-modulation fuze can not work naturally when the noise power that enter into the transmission band of the fuze reaches definite value.So it can make use of the conclusion to jam pseudo-random code phase-modula- tion fuze.
