The invention discloses a foreign matter intrusion detection method, system and device and a storage medium. The method comprises the steps that echo signals generated when a radar scans a plurality of calibration objects are received; and obtaining an RCS value according to the echo signal of each calibration object, and if the RCS value of at least one target calibration object is continuously lower than a first preset threshold value within a preset time, obtaining a detection result of foreign matter invasion. According to the method, the condition that the calibration object is shielded by the foreign matter is indirectly detected through the descending condition of the RCS value of the calibration object, the condition that direct radar detection is inaccurate due to the fact that the RCS value of the foreign matter is small is avoided, the recognition rate of an intrusive target can be increased, and the working distance of radar detection is greatly extended.

    本申请公开了一种异物侵入检测方法、系统、设备和存储介质,该方法包括:接收雷达扫描多个标定物的回波信号;根据每个标定物的回波信号获得RCS值,若至少一个目标标定物的RCS值在预设时间内连续低于第一预设阈值,则得到有异物侵入的检测结果。通过标定物的RCS值的下降情况间接检测有异物遮挡标定物,避免因异物的RCS值较小而导致的雷达直接检测不准确的情况,能够增强侵入目标的识别率,并使雷达检测的工作距离大大延伸。
