脉间相干多普勒声纳具有响应速度快、精度高等优点，在实验室和海上得到了广泛的应用。然而，距离和速度模糊的发生带来了严重的限制声纳的更一般的应用。处理模糊度的一种方法是实现双脉冲间隔方法，该方法可以提供可接受的模糊度速度，同时需要不复杂的设备。本文对三种测量误差进行了分析。一是作为测量误差的一个界的理论分析。第二种是通过模拟进行的数值分析，最后是在实验室中进行的实验分析。误差分析结果表明，双时间间隔脉冲-脉冲相干多普勒声纳能够以较高的精度扩大模糊速度。
As a Pulse-to-Pulse coherent Doppler sonar has advantages of quick-response and high degree of accuracy and precision, it becomes widely used in the laboratory and the sea. However, the occurrence of range and velocity ambiguities brings serious limitations on the more general applications of the sonar. One method to deal with the ambiguities is to implement a dual pulse interval method that can provide acceptable ambiguity velocity while requiring uncomplicated equipment. In this paper, three measurement error analyses are carried out. One is a theoretical analysis as one bound of measurement error. The second is a numerical analysis by simulations, and the last is experimental analysis in the laboratory. The results of the error analyses verified that the dual time interval pulse-to-pulse coherent Doppler sonar could enlarge the ambiguity velocity with high accuracy and precision.
