摘要
超宽带技术具有精度高、干扰低、穿透强等优点,其在环境复杂的室内定位中已经引起了人们极大的兴趣。同时近年来超宽带硬件在智能手机中的普遍安装,带动了超宽带在汽车行业的发展,超宽带数字钥匙已经成为手机和汽车等个人终端互通的重要通道。本文首先介绍了超宽带的原理及优点,然后阐述了数字钥匙、脚踢雷达、非接触式活体检测的应用现状亟待改进之处,最后展望了超宽带在车辆中未来的发展方向。
Ultra-wideband technology has the advantages of high accuracy,low interference and strong penetration,and its indoor positioning in complex environments has attracted great interest.Meanwhile,the common installation of ultra-wideband hardware in smartphones in recent years has driven the development of ultra-wideband in the automotive industry,and ultra-wideband digital keys have become an important channel for the intercommunication of personal terminals such as cell phones and automobiles.This paper firstly introduces the principle and advantages of UWB,then elaborates the current application status of digital key,kick radar and non-contact live detec⁃tion and the areas to be improved,and finally outlooks the development direction of UWB.
