摘要:
针对海上低截获通信应用,提出了一种低截获卫星通信技术并分析了其抗侦测性能。通过宽频带、低信息速率实现高增益扩频,系统设计上综合高工作频率、高增益天线等措施,降低卫星通信信号的功率谱密度;结合卫星链路计算,重点分析在同步轨道、低轨道电子侦察卫星侦测时的抗截获性能。理论分析和数值计算结果表明,增大扩频增益和天线增益可有效对抗同步轨道电子侦察卫星天线增益优势,对抗低轨道电子侦察卫星轨道优势,实现卫星低截获通信。

Abstract:
For maritime low intercept communication applications,a low detection probability satellite communication design is presented and its anti-detection performance is analyzed.High spread spectrum gain is got by maximizing the bandwidth and information rate.Together with other methods as high-frequency,high gain antenna are used in the system design,the power spectral density of the satellite communication signal is reduced as low as possible.By satellite link calculation,the anti-detection performance from the electronic reconnaissance satellite at geosynchronous orbit and at low orbit is analyzed.Theoretical analysis and numerical calculation results show that maximizing the spread spectrum gain and increasing the antenna gain are effective to be against the antenna gain superiority of the electronic reconnaissance satellite at geosynchronous orbit,and to be against the altitude superiority of the electronic reconnaissance satellite at low orbit.So the low detection probability satellite communication is realized.
Key words:  satellite communication  low detection probability communication  electronic reconnaissance satellite  spread spectrum communication
