摘　　要：针对TDRSS采用传统的PSK调制方式无法保证高速数传链路抗干扰性能的局限性,考虑在不增加系统带宽的前提下,结合频率跳变技术运用恒定包络、高频带利用率的MSK调制设计TDRSS信号形式,实现了大于信号本身带宽的躲避干扰。通过建立TDRSS通信系统模型开展仿真研究,验证了所提调制方式能够提高宽带噪声干扰抑制能力,并进一步对部分频带干扰抑制能力进行分析,为TDRSS高速数据传输过程中抗干扰的发展提供方法参考。Due to the deficiency of the traditional PSK modulation modes,the anti-jamming performance of TDRSS high-speed digital transmission link could not be guaranteed.Based on constant envelope and high spectral efficiency of MSK modulation,TDRSS signal form is designed using MSK modulation combining with frequency hopping technique without increasing bandwidth.Simulations are carried out by modeling TDRSS communication system.It is verified that the link signal type proposed in this paper could improve broadband noise interference suppression ability.Furthermore,the partial band interference suppression capability has been analyzed which could provide methodology references in the anti-jamming development of TDRSS high-speed data transmission link.
