The ship navigation information processing system of digital signal processor is designed to suppress interference information and improve the information processing effect. Trigger signal and intermediate frequency signal are generated by radar front end. Through A/D converter, the digital navigation information is collected in the generated signal, adopting digital signal processor for information processing with frequency interference suppression and accumulation of the pulse processing algorithms. The navigation information is separated according to the mutual information gradient to suppress the same frequency interference of navigation information. Information processing results are presented through radar display processing terminal. Experiments show that the system can obtain clear navigation radar signal map and effectively collect digital navigation information. The system can suppress interference information accurately and improve the effect of information processing. In different channel states, the information transmission rate of the system is fast.
