摘要

这封信通过概述一个数学框架来剖析导频信号和不完全信道估计的影响，研究了联合雷达通信系统中隐蔽传感和通信之间的相互作用。为关键性能度量导出了封闭形式的表达式，包括中断概率（OP）、遍历容量（EC）、互信息（MI）和检测错误概率（DEP）。在满足隐蔽传感要求和通信性能的同时，提出了一种联合雷达功率和时间资源分配方案。理论分析和仿真结果揭示了雷达发射功率设置对OP和DEP性能趋势的影响，并强调了MI和EC之间以及训练和数据传输时间之间的权衡。

Study on Joint Covert Sensing and Communication Systems

This letter investigates the interplay between covert sensing and communication in joint radar-communication systems by outlining a mathematical framework to dissect the influence of pilot signals and imperfect channel estimation. Closed-form expressions are derived for key performance metrics, including outage probability (OP), ergodic capacity (EC), mutual information (MI), and detection error probability (DEP). Moreover, a joint radar power and time resource allocation scheme is developed to maximize the MI while satisfying both covert sensing requirements and communication performance. Theoretical analyses and simulation results reveal the impacts of radar’s transmit power setting on the OP and DEP performance trends and highlight the trade-offs between MI and EC, as well as between training and data transmission times.
