摘要

摘要:
针对卫星通信面临的不同类型的干扰，以频移键控(FSK)调制通信信号为研究对象，重点对单音、多音、窄带、多音窄带、噪声调幅、噪声调频、噪声调相、线性调频、脉冲干扰9种干扰对抗条件下的误码率与信干比之间的关系进行研究。通过仿真提供了不同频偏、不同信干比情况下，不同干扰样式对FSK调制传输系统的恶化程度，并得出最佳干扰样式，同时给出了不同频偏、不同干扰样式情况下实现通信阻断（误码率大于10⁻²）需要的最高信干比。当信干比小于0 dB时，单音干扰和噪声调频干扰对系统恶化程度更严重；当信干比大于0 dB时，噪声调频干扰、多音窄带干扰和脉冲干扰具有更好的干扰效果。在不同频偏情况下实现通信阻断，脉冲干扰付出的功率代价最小。

Abstract:
In view of the different types of jamming faced by satellite communication, frequency-shift keying (FSK) modulated communication signal was taken as the research object, and the relationship between the bit error rate and the signal-to-jamming ratio was mainly studied under the nine countermeasure conditions of jamming, such as single-tone, multi-tone, narrowband, multi-tone narrowband, noise amplitude modulation, noise frequency modulation, noise phase modulation, linear frequency modulation jamming, and pulse jamming. The deterioration degree of the FSK modulated communication system with different types of jamming in the case of different frequency biases and signal-to-jamming ratios was obtained through simulation, and the optimal jamming type was obtained. At the same time, the maximum signal-to-jamming ratio required to block communication (with a bit error rate greater than 10⁻²) under different frequency biases and different types of jamming was obtained. When the signal-to-jamming ratio was less than 0 dB, the single-tone jamming and noise frequency modulation jamming caused more serious system deterioration. When the signal-to-jamming ratio was greater than 0 dB, the noise frequency modulation jamming, the multi-tone narrowband jamming, and the pulse jamming exhibited better jamming effect. In the case of different frequency biases, the pulse jamming required the minimum power to block communication.
