汽车雷达传感器即使在多目标情况下也被用于同时测量目标的距离、方位角和径向速度。对先进驾驶辅助系统(ADAS)如公路场景的目标跟踪而言,单一目标测量数据是必需的。在典型的城市交通情况下,对雷达测量值添加上每个受检目标(如车辆)的横向速度分量是很有意义的。本文表明,即便在单项观测状态下也能量测出扩展目标的横向速度。在目标上的驻留时间应当足够大的情况下要求汽车雷达传感器有高的谱分辨率。
Automotive radar sensors are used to simultaneously measure the distance, azimuth and radial speed of a target, even in multi-target situations. Single target measurement data is required for target tracking of advanced driver assistance systems (ADAS) such as road scenes. In a typical urban traffic scenario, it makes sense to add the horizontal velocity component of each surveyed target (such as a vehicle) to the radar measurements. This paper shows that the lateral velocity of the expansion target can be measured even in the single observation state. Vehicle dwelling radar sensors are required to have a high spectral resolution when the dwell time on the target should be large enough.
