摘要:

联合雷达通信(JRC)系统可以同时进行雷达探测和通信。在本文中,我们提出了一种适用于多径环境的双基地JRC系统。基于一种新的联合波形,设计了一种用于目标检测和信道估计的联合检测过程。同时,提出了一种利用从检测过程中获取的信道状态信息的低成本信道均衡方法。数值结果表明,该系统的误符号率与二进制频移键控系统的误符号率相近,而在多径环境下信噪比要求比单径环境下高不到2 dB,从而达到10-5的误符号率。此外,联合检测过程不需要知道嵌入信息,检测性能对未知信息具有鲁棒性。

英文摘要:

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.
