【讲座信息】

在提升无线电频谱利用效率及防干扰服务方面要借助于大胆创新的概念。频谱堵塞和动态频率分配领域中最紧迫的问题之一是在雷达和通信之间提供无可争议的共享带宽。这激发了近年来对于设计雷达与无线服务共享带宽的同时工作思路。与频谱感知、认知无线电及认知雷达共存的设计方法不同，最新的研究正在转向将通信信号嵌入雷达波形的设计方法。如此，通信系统可利用现有雷达设施资源，包括高功率、大带宽、高质量的硬件。本报告针对这一问题，讨论雷达与通信双功能技术，使雷达能够容纳语音和数据传输，从而促进雷达和通信系统的技术进步。开发了将信息嵌入雷达脉冲发射的新型信令方案。另外，考虑不同的天线配置情况，包括MIMO雷达，通过将幅度和相移键控调制与波形分集和空间自由度相结合来实现高数据速率通信，并同时满足整体功率约束。

There is a growing need for bold and new concepts with the potential to contribute towards significant improvements in the efficiency of radio spectrum utilization and protection from interfering services. One of the most pressing problems in the area of spectral congestion and dynamic frequency allocations is to provide uncontested shared bandwidth between radar and communications. This has recently spurred extensive efforts towards devising solutions for simultaneous operations of radar target illuminations and wireless services sharing the same frequency bandwidth. Unlike the general approach of coexistence, which predicates on cognitive radio and cognitive radar for spectrum sensing and utilization, recent research is moving to enable

the embedding of communication signals into radar waveforms. In so doing, the communication systems capitalizes on the resources of existing radar infrastructure, including high power, large bandwidth, and high quality hardware. This tutorial establishes and promotes the area of dual system functionality, allowing radar to house voice and data transmission, leading to technological advances in radar and communications systems. The research develops novel signaling schemes for embedding information into the radar pulsed emissions, which, in most cases, is blind to the primary radar operation. It considers different antenna configurations, including multiple-input multiple-output (MIMO) radars and achieves high data rate communications by combining amplitude and phase-shift keying modulations with waveform-diversity and spatial degrees of freedom, while satisfying an overall power constraint.
