Simulation Study of Confrontation Efficiency of Noise Jamming to DSSS Modulation System

With the rapid development of electronic countermeasure technology, communication countermeasures equipment is becoming more and more widely used in electronic countermeasures. Combing with the technical characteristics of communication countermeasures equipment, the relation between the error rate and jamming signal ratio (JSR), signal noise ratio (SNR) of communication equipment using direct sequence spread spectrum (DSSS) modulation technology under the condition that noise jamming is taken as main jamming mode, the results show that the interference effect is better than the effect of broadband interference. The conclusion is of reference value for further studying the jamming technique and jamming effect.
