论文摘要
分析多输入多输出（MIMO）双功能雷达通信（DFRC）系统的性能结合是一个基本问题。为此，我们在雷达性能的约束下得出了对通信功能的性能。为了促进分析，我们考虑了一个玩具示例，其中只有一个沿链接用户具有一个接收天线和一个雷达目标。在这种简化的情况下，我们获得了性能结合的分析表达式和相应的波形设计策略，以实现结合。结果揭示了通信和雷达性能之间的权衡，并且何时可以在这两个功能之间共享传输能量时。
It is a fundamental problem to analyse the performance bound of multiple-input multiple-output (MIMO) dual-functional radar-communication (DFRC) systems. To this end, we derive a performance bound on the communication function under a constraint on radar performance. To facilitate the analysis, we consider a toy example, in which there is only one down-link user with a single receive antenna and one radar target. In such a simplified case, we obtain an analytical expression for the performance bound and the corresponding waveform design strategy to achieve the bound. The results reveal a tradeoff between communication and radar performance, and a condition when the transmitted energy can be shared between these two functions.
