摘要

车载雷达是减少交通事故的重要设备。直接序列超宽带(DS-UWB)雷达作为一种高精度测距雷达，近年来得到了广泛的研究。在本文中，我们假设车队环境下所有车辆都配备DS-UWB雷达。本文的目的是展示在DS-UWB自动速度控制应用时的排特性。此外，我们提出了使用变长扩频码的DS-UWB雷达。通过计算机模拟对该方案进行了评价。仿真结果表明，该系统不仅可以提高测距时间，而且可以在处理时间和车辆跟随精度之间取得平衡。

Platoon characteristics of automatic vehicle speed control for vehicles equipped with DS-UWB radar

A vehicular radar is an essential device for reducing traffic accidents. Direct sequence ultra wideband (DS-UWB) radar has been studied in recent years as a kind of radar enabling high — precision ranging. In this paper, we assume that all vehicles are equipped with the DS-UWB radar in the platoon environment. The purpose of this paper is to show the platoon characteristics when automatic speed control is applied with DS-UWB. Additionally, we propose DS-UWB radar using variable length of spreading codes. The proposal is evaluated by computer simulations. Some simulation results show that not only ranging time could be improved by the proposed system but also trade-off between processing time and vehicle following accuracy.
