Based on the principle of DSSS,a PN sequence DSSS simulation model was established in this paper.Then the performance of system in band jamming,single tone jamming,and pulse jamming were analyzed and simulated respectively by using Matlab 7.0,also the impact of coding and synchronization on its performance were studied. Finally,the corresponding conclusion of antijamming performance was summarized.
