脉间相干多普勒声纳以其高精度和高分辨率在实验室和野外都有着广泛的应用。然而，距离和速度模糊的发生带来了严重的限制，该技术的更一般的应用。处理速度模糊度的一种方法是引入双脉冲重复间隔，其可以提供可接受的速度模糊度并且需要不复杂的设备。实验在频率为200KHz、脉冲间隔为40ms和60ms的水槽中进行。结果表明，该方法是有效的，并产生高质量的速度数据，以跟踪目标的速度在有限的范围内在水中。
With high accuracy and resolution Pulse-to-Pulse coherent Doppler sonar is wildly used in both laboratory and field application. However, the occurrence of range and velocity ambiguities brings serious limitations on the more general application of the technique. One method to deal with speed ambiguities is to import a dual pulse repetition interval which can provide acceptable speed ambiguities and requires uncomplicated equipment. The experiments are carried out under the frequency of 200KHz with 40ms and 60ms pulse intervals in a water tank. The results show that this method is efficient and produces high quality velocity data to track the velocity of an object in a limited range in water.
