摘　　要：目前,超声波传感器主要用于低速运动的自主式移动机器人短距离测量,采用的测距方法多把串音干扰看作有用信号的干扰项,尽可能排除。基于远距离超声波传感器,本文利用串音干扰设计了一种适用于高速行驶的陆地自主车进行远距离测量的方法。实验结果表明此方法的可靠性和精度都能满足陆地自主车的距离探测要求。So far, the ultrasonic sensor has been mainly used in the short distance measurement for autonomous mobile robot which moves slowly, the algorithm of distance measurement has tried them best to exclude the crosstalk which has traditionally is considered to be undesirable for signals. On the base of successful development of ultrasonic sensor for long operating distance, this paper pre- sents a novel method relies on the crosstalk phenomenon and the ultrasonic sensor can be used for long distance measurement...
