摘要
雷达嵌入式通信(REC)是一种使雷达与通信共用频谱的隐蔽通信方式,通过在高功率雷达后向散射回波中嵌入通信波形完成低截获概率(LPI)通信.传统的REC波形性能分析通常将通信可靠性和LPI性能分开考虑,忽略了其综合性能.基于处理增益提出了处理增益优势这一分析指标,对3种REC波形的通信可靠性能、LPI性能以及综合性能进行分析,为满足不同需求下REC通信的波形及参数选择提供了全新参考.仿真结果证实了利用处理增益优势分析REC波形性能的正确性和可行性.
Abstract
Radar-embedded communication(REC)is a covert communication method that enables radar and communication to share spectrum,and it achieves low probability of interception(LPI)communication by em-bedding communication waveforms in high-power radar backscattered echoes.Communication reliability and LPI performance are usually considered separately in the traditional REC waveform analysis,and thus,the compre-hensive performance of REC waveforms is often ignored.The index of processing gain advantage is proposed based on the processing gain,and the communication reliability performance,LPI performance and comprehen-sive performance of three REC waveforms are analyzed,which provides a new reference for waveform and param-eter selection of REC communication under different requirements.The simulation results confirm the correctness and feasibility of analyzing the performance of REC waveforms with the processing gain advantage.
