First, the principle of the three pseudo-random code fuzes-pseudo-random code phase modulation fuze, pseudo-random code phase modulation and pulse amplifier modulation combined fuze, and pseudo-random code phase modulation and pseudo-random pulse position modulation combined fuze are inctroduced briefly. Thereafter, their equations of reconnaissance range are deduced in detail, on this basis, their performances of countereconnaissance are analyzed through an example. Then, their probabilities of detection are deduced by the Neyman-Pearson theorem. At last, the models of probability of intercept are presented by utilizing the functions of window, and their probabilities of intercept are deduced and simulated in detail.
