A distance measuring apparatus and a method of operating the same are provided. The distance measurement apparatus may include: a transmitter configured to transmit a sensing signal toward a target object based on a transmission signal; a receiver configured to detect the sensing signal and output a reception signal corresponding to the sensing signal; and a processor configured to correct the received signal using a baseline having a peak value that varies according to a time index, and determine a distance to the target object based on a cross-correlation signal indicating a cross-correlation between the corrected received signal and the transmitted signal. 提供了一种距离测量设备及其操作方法。距离测量设备可以包括：发送器，被配置为基于发送信号朝目标对象发射感测信号；接收器，被配置为检测感测信号并输出与感测信号相对应的接收信号；以及处理器，被配置为使用具有根据时间索引而变化的峰值的基线来校正接收信号，并且基于指示校正后的接收信号与发送信号之间的互相关的互相关信号来确定到目标对象的距离。
