摘要
隐蔽通信技术能够隐藏通信的存在,实现信号的低概率检测,在军事等需要高保密性的领域中应用广泛。为了实现低概率检测通信,提出了一种低概率检测信号的设计方案,该方案将符号扩频和双层多参数加权分数傅里叶变换相结合起来,生成了具有强隐蔽性的信号。仿真实验证明,所提出方案生成的隐蔽信号无论是在时域频域还是统计域都具有很强的隐蔽性,并且在低信噪比下也具有良好的可靠性。
In order to achieve low probability detection communication,this paper proposes a design scheme for low probability detection signals.The scheme combines symbol spreading and double layers multiple parameters weighted-type fractional Fourier transform to generate a signal with strong covertness.Simulation experiments demonstrate that the covert signal generated by the proposed scheme has strong covertness in both time domain,frequency domain and statistical domain,and also has good reliability at low signal-to-noise ratio.
