    • A radar sensor system and method for ascertaining whether an unattended child is present within an automotive vehicle. The radar sensor system carries out the method and includes a transmitter, at least one sensor, and processing circuitry. The method includes the steps of: illuminating at least one occupiable position within the vehicle with radiation of multiple frequencies; generating radar sensor signals from reflections of the transmitted radiation, a plurality of the radar sensor signals corresponding to different frequencies; and operating the processing circuitry for generating and determining if a first indicator value indicative of motion in the occupiable position satisfies a first predetermined criteria and, if so, generating and determining a second indicator value indicating a degree of repetitive pattern within the radar sensor signals, and determining presence of an unattended child in the vehicle if the second indicator value satisfies a second predetermined criteria.
    • 用于确定无人照顾儿童是否存在于机动车辆内的方法使用包括发射机(204)和至少一个传感器和处理电路的雷达传感器系统(200)。 该方法包括:用辐射照射车辆内的至少一个可占据位置,该辐射呈现多个频率; 由发射辐射反射的辐射产生雷达传感器信号,对应于不同频率的多个雷达传感器信号; 操作所述处理电路,用于基于所述雷达传感器信号产生第一指示值,所述第一指示符值指示与所述可占据位置相关联的运动程度; 确定所述第一指示符值是否满足第一预定标准; 如果第一指示符值满足第一预定标准,则基于雷达传感器信号产生第二指示符值,第二指示符值指示雷达传感器信号内的重复图案的程度; 以及如果所述第二指示符值满足第二预定标准,则确定所述机动车辆中存在无人值守的小孩。
