Abstract:
The starting probability of pseudo-random code fuze(PRCF) is deduced under suppressing noise FM jamming by setting up an analysis model of the starting probability.The influence of suppressing noise FM jamming on the starting probability of the PRCF is analyzed by simulation.The simulation results show that the starting probability can be improved by increasing the pseudo-random code period and receiver bandwidth and by minishing the code-element width.The starting probability can be reduced by increasing jamming to signal ratio(JSR) of a reaching receiver and by minishing jamming bandwidth and collimating error of jamming carrier wave frequency.The Doppler frequency leaves a small influence on the starting probability when it is less than 5 kHz,but the influence becomes greater with the increase of Doppler frequency.This study can provide a method of assessing anti-jamming performances of fuzes.
