Study on jamming effect of pseudo-random binary-phase-coded fuze based on starting probability

Under radio frequency (RF) noise jamming, jamming effect of pseudo-random binary-phase-coded fuze (PRBPCF) is researched based on its starting probability. Analysis model of starting probability is set up, and the starting probability of the PRBPCF is deduced under RF noise jamming, Factors influencing the starting probability are discussed. The simulation results show that jamming effect of the PRBPCF is affected not only by jamming to signal ratio(JSR) of reaching receiver and interference bandwidth, but by pseudo-random code period, code-element width, receiver bandwidth, Doppler frequency. Theory and practice prove starting probability is practicable to be used to evaluate jamming effect of the PRBPCF, and can be applied to engineering practice.
