论文摘要
雷达检测和通信可以在关节雷达通信（JRC）系统中同时进行。在本文中，我们提出了一个适用于多路径环境的Bistatic JRC系统。基于新型的关节波形，为目标检测和通道估计设计了一个联合检测过程。同时，提出了一种利用从检测过程中获取的通道状态信息的低成本通道均衡方法。数值结果表明，所提出的系统的符号错误率（SER）与二进制频移键系统的符号错误率（SER）相似，并且在多路径环境中，信号与噪声比的要求相比，与单路环境中的SER达到10-5相比，噪声比的要求更高。此外，联合检测过程不需要嵌入信息的知识，并且检测性能对未知信息具有鲁棒性。
Radar detection and communication can be operated simultaneously in joint radar-communication (JRC) system. In this paper, we propose a bistatic JRC system which is applicable in multi-path environments. Basing on a novel joint waveform, a joint detection process is designed for both target detection and channel estimation. Meanwhile, a low-cost channel equalization method that utilizes the channel state information acquired from the detection process is proposed. The numerical results show that the symbol error rate (SER) of the proposed system is similar to that of the binary frequency shift keying system, and the signal to noise ratio requirement in multi-path environments is less than 2 dB higher compared with that in single-path environment to reach a SER of 10-5. Besides, the knowledge of the embedded information is not required for the joint detection process and the detection performance is robust to unknown information.
