摘要
提出了一种利用可编程逻辑器件实现串行数字相关来完成超声波测距的方法.相对于以往利用单脉冲实现的超声波测距,在峰值功率和平均功率都较小时,它有有效测量距离远、精度高和体积小等优点,可广泛应用于汽车防撞、海洋探测等领域.
This paper introduces a method to implement ultrasonic range\|measures with serial digital correlation based on CPLDs. Compared with those ultrasonic range\|measures implemented by using single pulse, when the transmitting power and mean power are both smaller, it has a number of merits such as wide range, high precision and small volume, etc. So this method can be widely used in preventing car collision and ocean exploration.
