基于邻接表的5G基站和雷达并发的方法
Method of concurrent 5g base station and radar based on adjacency table
5G已经选择了厘米波和毫米波作为主频段，这两个频段也归属精密定位、跟踪等功能的雷达常用的频段之中。5G基站引入了大规模天线(massive MIMO)，和雷达相控阵天线基本一致。主选TDD模式，和脉冲雷达同一频段内先发后收需求模式一样，已经具备了雷达的所有硬件要求，本文将5G基站与雷达组合起来，在自包含帧结构和灵活子帧引入雷达发送信号和接收处理，可以兼容现有5G帧结构，通过基站邻接表相互避让相邻基站的干扰，通过相控阵或多基站协同检测主动检测目标，在一个基站同时提供通信和雷达功能。具有投入少，效益高的好处。在安保等领域能发挥重要作用。针对应用场景的不同，可以定位车辆，人体，飞行物（如无人机）等，应用前景广阔。

I The centimeter wave and millimeter wave has been selected as the main frequency band for 5G, and these two frequency bands also belong to the favorite frequency band of precision positioning and tracking radar. 5g base station introduces massive MIMO, which is basically the same as radar phased array antenna. TDD mode is selected as the main mode, which is the same as the demand mode of transmitting and receiving in the same frequency band of pulse radar. It has all the hardware requirements of radar. This article combines 5g base station with radar, and introduces radar signal transmission and receiving processing in self-contained frame structure and flexible sub frame, which is compatible with the existing 5g frame structure; The interference of adjacent base stations is avoided by neighbor list;The active detection target is detected by phased array or mA Method of introducing radar detection mechanism into gNBulti-basestation cooperative detection. The communication and radar functions are provided in one base station at the same time. It has the advantages of less investment and high efficiency and can be used in different scenarios，such as detection of illegal invasion UAVs etc.
