论文摘要
一个大型网络采用集成感应和通信（ISAC），研究基站（BS）的单个传输信号同时使用雷达和通信模式。我们考虑在传输BS处的被动雷达和单恒定检测处的双性检测。由于信号组件中的双路径损失，干扰物具有直接链接，因此雷达模式性能比通信模式更脆弱。为了应对这一点，我们提出：1）一种新型的动态传播策略（DTS），2）通过BS的合作检测关节单恒定和Bistation检测。我们分析了单恒定，族裔和关节检测的性能。我们表明，低成本无源雷达的密集部署随着距离较远目标的检测提供了鲁棒性。在某些情况下，可以通过联合检测来实现雷达绩效的显着改善，而使用一种策略对其他策略有益。我们的结果强调，使用DTS，我们能够以数量成本显着提高雷达检测的质量。此外，DTS会导致通信模式的某些性能恶化；但是，雷达模式获得的收益要高得多。我们表明，联合检测和DT一起可以从传统的雷达网络中显着改善雷达的性能。
A large network employing integrated sensing and communication (ISAC) where a single transmit signal by the base station (BS) serves both the radar and communication modes is studied. We consider bistatic detection at a passive radar and monostatic detection at the transmitting BS. The radar-mode performance is significantly more vulnerable than the communication-mode due to the double path-loss in the signal component while interferers have direct links. To combat this, we propose: 1) a novel dynamic transmission strategy (DTS), 2) joint monostatic and bistation detection via cooperation at the BS. We analyze the performance of monostatic, bistatic and joint detection. We show that bistatic detection with dense deployment of low-cost passive radars offers robustness in detection for farther off targets. Significant improvements in radar-performance can be attained with joint detection in certain scenarios, while using one strategy is beneficial in others. Our results highlight that with DTS we are able to significantly improve quality of radar detection at the cost of quantity. Further, DTS causes some performance deterioration to the communication-mode; however, the gains attained for the radar-mode are much higher. We show that joint detection and DTS together can significantly improve radar performance from a traditional radar-network.
