The invention relates to the technical field of vehicles, in particular to a shielded vehicle detection method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining echo data in a vehicle driving direction; performing time-frequency analysis on the echo data to obtain a time-frequency diagram, extracting micro-Doppler features of the time-frequency diagram, and identifying whether the micro-Doppler features are preset features; if the micro-Doppler feature is the preset feature, it is judged that there is a traverse shielding vehicle in the vehicle driving direction, and otherwise, it is judged that there is no traverse shielding vehicle in the vehicle driving direction. Therefore, the problems that in the prior art, the scanning range and precision of a detector are limited, accurate detection of the shielded and transversely-penetrating vehicle cannot be achieved, recognition is difficult, and safety is poor are solved.

    本申请涉及车辆技术领域,特别涉及一种遮挡车辆检测方法、装置、车辆及存储介质,其中,方法包括:获取车辆行驶方向上回波数据;对回波数据进行时频分析得到时频图,提取时频图的微多普勒特征,并识别微多普勒特征是否为预设特征;若微多普勒特征为预设特征,则判定车辆行驶方向上存在横穿遮挡车辆,否则判定车辆行驶方向上不存在横穿遮挡车辆。由此,解决了相关技术中探测器的扫描范围和精度有限,无法实现遮挡横穿车辆的精准检测,存在识别困难,安全性差等问题。
