摘要
随着电子对抗技术的飞速发展,通信对抗装备愈来愈广泛地用于电子对抗领域。结合通信对抗装备技术特征,本文重点研究采用DSSS(直接序列扩频)调制技术的通信装备在以噪声干扰为主要方式对抗条件下,误码率与干信比、信噪比之间的关系,得到了在同等条件下,部分频带干扰效果优于宽带干扰效果的结论,该结论对进一步深入研究干扰技术和干扰效果具有参考价值。
With the rapid development of electronic countermeasure technology,communication countermeasures equipmentis becoming more and more widely used in electronic countermeasures.Combing with the technical characteristics of communicationcountermeasures equipment,the relation between the error rate and jamming signal ratio(JSR),signal noise ratio(SNR)ofcommunication equipment using direct sequence spread spectrum(DSSS)modulation technology under the condition that noisejamming is taken as main jamming mode,the results show that the interference effect is better than the effect of broadbandinterference.The conclusion is of reference value for further studying the jamming technique and jamming effect.
