摘要
基于充分利用阵列天线资源,实现雷达与通信信号同时传输的目的,文中提出了一种新型的雷达通信一体化信号调制解调方法。一体化信号的离散频谱是由经特定频率采样的雷达与通信信号的离散频谱交叉形成的。时域上,该一体化信号是由改进的雷达与通信信号相加形成的。文中提出的方法所对应的一体化系统具有许多优点,包括适用的信号形式多样,安全性高,误码率为传统通信模式的一半等。
To make full use of resources of the array antenna to transmit the radar and communication signal simultaneously,this paper proposes a novel modulation and demodulation method of radar and communication integrated signal. Discrete spectrum of the integrated signal is formed by interlacing discrete spectrums of radar and communication signals which are sampled at a specified frequency. In time domain,the integrated signal is formed by adding modified radar and communication signals. The integrated system corresponding to the novel method in this paper has advantages,including high diversity of signals applicable to it,great security,lower BER（ bit error rate） just half of that of the traditional communication systems and so on.
