摘　　要：随着社会的快速发展,道路中机动车的数量呈爆炸式增长,城市交通管理系统亟需一种能够应对城市高密度、缓慢车流的新型交通监测方式。本文设计一种3D交通雷达采用宽波束来覆盖所有车道,同时对监测区域的所有目标进行测速、测距和测角来精确定位,并可对目标进行分类。本雷达采用多频连续波在频域处理进行高分辨率测速和高精度测距,并通过双接收天线进行数字和差波束获得高测角精度。最终研制出了能够切实应用到城市交通管理系统的天馈和收发一体集成的小型化3D交通雷达。With the rapid development of society,the number of vehicles on the road has increased dramatically.It is urgently necessary for urban traffic management systems to have a new type of traffic monitoring method that can cope with high density and slow traffic flow in cities.In this paper,a 3D traffic radar is designed to use a wide beam to cover all lanes,and at the same time,all targets in the monitoring area are measured by speed,range and angle to accurately locate them and classify the targets.This radar uses multi-frequency continuous wave processing in the frequency domain for high-resolution speed measurement and high-precision distance measurement,and digital and differential beams through dual receiving antennas to achieve high angular accuracy.In the end,a miniaturized 3D traffic radar was developed to practically apply to the integration of antenna feed and transceiver in urban traffic management systems.
