通过配置及模式设定优化车载毫米波雷达探测距离的研究

Research on Optimizing Detection Range of Vehicle-Mounted Millimeter-Wave Radar by Configuration and Mode Setting

车载毫米波雷达,是当前高等级自动驾驶系统中不可或缺的传感器,相对于其它类型传感器,在探测目标的距离和速度方面有明显优势。目前,高等级自动驾驶系统对距离探测的要求需达到190m以上,但由于一款车载毫米波雷达允许的尺寸、制造工艺等对其性能有较大的限制,无论是在仿真测试还是实车测试,探测距离均难以满足需求。本文通过DID配置,对车载毫米波雷达工作调制模式进行设置等尝试对探测距离进行优化,使其进一步满足车载应用场景的需求。

Millimeter wave radar is an indispensable sensor in the current high-level auto drive system.Compared with other sensor, it has obvious advantages in detecting the distance and speed of targets. At present,the high-level auto drive system requires a distance detection of more than 190m. However, the allowable size and manufacturing process of an on-board millimeter wave radar have great limitations on its performance. The detection distance is difficult to meet the requirements in both simulation test and real vehicle test. This paper attempts to optimize the detection distance through DID configuration, combined working modulation mode adjustment and so on,so as to further meet the needs of vehicle application scenarios.
