    • A distance measuring method and apparatus in which first and second pseudo random signals which are the same in pattern but slightly different in period are generated to obtain a correlation output of the first and second pseudo random signals before transmission thereof as a reference correlation output, and the first pseudo random signal is directly transmitted toward a target or alternatively a carrier wave is modulated by the first pseudo random signal and transmitted toward the target. A correlation output of the signal reflected and received from the target and the second pseudo random signal is detected and the distance to the target is measured from the time interval between the reference correlation output and the received correlation output. Alternatively, the modulated carrier wave reflected and received from the target and the second pseudo random signal are subjected to correlation processing to detect a correlative modulated carrier wave and the correlative modulated carrier is subjected to orthogonal detection by a reference carrier wave thereby obtaining a target detection output. Then, the distance to the target is measured from the time interval between the reference correlation output and the target detection output.
    • 产生距离测量方法和装置,其中以模式相同但周期稍有不同的第一和第二伪随机信号被产生,以获得其发送之前的第一和第二伪随机信号作为参考相关输出的相关输出,以及 第一伪随机信号被直接发送到目标,或者替代地,载波被第一伪随机信号调制并被发送到目标。 检测从目标反射和接收的信号与第二伪随机信号的相关输出,并且从参考相关输出和接收到的相关输出之间的时间间隔测量到目标的距离。 或者,对从目标反射和接收的调制载波和第二伪随机信号进行相关处理以检测相关调制载波,并且通过参考载波对相关调制载波进行正交检测,从而获得目标检测 输出。 然后,从参考相关输出和目标检测输出之间的时间间隔测量到目标的距离。
