【摘要】 在电子信息系统对抗中，雷达、通信、侦察机和干扰机等多种电子设备通过简单的功能叠加式配备于作战平台已经难以应对敌方的综合性电子兵器，因此，多种电子设备的综合一体化是现代战争环境装备发展的必然趋势。其中，作为战场“千里眼”和“顺风耳”的雷达和通信设备无论在硬件结构还是在信号处理方法上都具有极强的相似性，两者的有机结合具有很强的实现性。因此，通感一体化(DFRC)系统受到了广泛的关注。其中，DFRC信号设计是DFRC系统研究的关键科学问题之一，通过电磁频谱共享方式，在空域、时域以及频域等多个维度上，同时实现雷达探测和信息通信两种功能。该文对以感知功能(雷达探测功能)为主功能的DFRC信号设计方法进行了深入、系统的综述。该文简要介绍了面向战场环境的DFRC系统的相关项目，进一步讨论了DFRC信号设计的研究进展。并在最后总结全文并对未来的研究方向进行了展望。更多还原

【Abstract】 During the confrontation of electronic systems, it is challenging to deal with the enemy’s comprehensive electronic weapons by simply combining electronic equipment, such as radar, communication,surveillance, and jammers. Hence, to meet the requirements of a modern war environment, the comprehensive integration of various electronic equipment is an inevitable trend. Radar and communication equipment, which are viewed as forward eyes and ears, are very similar in hardware structure and signal processing methods. In this regard, the organic union of these two is plausible. As a result, the Dual-Function Radar and Communication(DFRC) system has received a lot of attention, where integrated waveform design is one of the key scientific issues. The DFRC waveform primarily refers to the transmit waveform that realizes radar detection and information communication functions simultaneously in multiple dimensions, such as space, time, and frequency domains, through electromagnetic spectrum sharing. This paper provides a fundamental review of the radarcentric DFRC waveform design. Initially, this paper presents a brief overview of the radar-centric DFRC system’s application scenarios. Then, the progress of radar-centric integrated waveform design research is discussed. Finally, some closing remarks and potential future research directions are provided.更多还原
