音频干扰对FSK调制系统的对抗效果研究

Research into The Countermeasure Effect of Audio Jamming to FSK Modulation System

随着电子对抗武器装备的不断发展,对于电子对抗武器装备的研究逐步受到重视。重点研究采用频移键控(FSK)调制技术的装备在以音频干扰为主要方式的对抗条件下,误码率与干信比、信噪比之间的关系,并得出科学的结论。研究中以单音干扰为例,进行了仿真研究。仿真结果表明该成果对进一步研究干扰技术和干扰效果具有一定的参考价值。

Along with the continuous development of electronic countermeasure weapon equipment, the study of electronic countermeasure weapon equipment is attached importance gradually. This paper makes focal point of study on the relationship between bit error rate （BER） and jamming to signal rate （JSR）,signal tonoise rate （SNR） of equipment that uses frequency shift keying （FSK） modulation technology, under the countermeasure condition in which audio jamming is taken as the main mode,and gain a scientific conclusion. In this study the single audio jamming is taken as an example, and the simulative study is performed. The simulation results show that the study pro- vides valuable reference for the further study of jamming technology and effect.
