【摘要】 随着通信感知一体化技术的不断发展，移动通信系统将集成雷达传感功能，从而促进智慧城市、智慧交通等新型智能化应用。由于传统雷达单基站的感知精度和感知范围有限，不能发挥大规模网络化移动通信系统的特有优势。因此，提出了一种适用于移动通信系统的多基站协作感知方法。该方法混合波达方向和到达时间差对目标进行3-D联合定位。理论分析结果和仿真结果均表明，该定位算法在小噪声条件下可以达到克拉美罗下界。更多还原

【Abstract】 With the continuous evolution of integrated sensing and communication technology, mobile communication systems are integrating radar sensing to facilitate emerging smart applications, such as smart cities and intelligent transportation. Given the limited sensing accuracy and range of traditional radar with a single base station, which does not leverage the unique advantages of large-scale networked mobile communication systems, a multi-base station cooperative sensing method suitable for mobile communication systems is proposed. This method employs a mix of the direction of arrival and the time difference of arrival for three-dimensional joint localization of targets. Both theoretical analysis and simulation results demonstrate that this localization algorithm can achieve the Cramér-Rao lower bound under low noise conditions.更多还原
