对潜艇超长波通信系统的干扰仿真研究

he technology of DS-SS, developing firstly in applying for military correspondence, is one kind of information processing technology and has been applied in Submarine Communication System of ELF Waves widely. MSK is one numeral modulation technology which has the merits of small band width, central frequency spectrum, continuous phase, constant scope and more information transmitting in the same band, so MSK is used to Submarine Communication in many countries recently. The paper analyzes characteristic of MSK based on DS-SS technology, analyzes and compares the jamming effect based on MATLAB environment，and gives the conclusions. It’s of real significance for us to improve the battle effectiveness.
