摘要
声学多普勒流速是根据声学多普勒原理,用矢量合成法测量水流的垂直剖面分布,它被用来遥测较大范围内的水流速度。文章分析了流速测量的脉冲相干信号处理方法的原理,根据回波信号产生机理,分别建立了宽、窄带回波信号散射叠加信号模型,并利用蒙特卡洛法对比分析了不同条件下的宽、窄带测速性能。
The acoustic Doppler velocity is based on the principle of acoustic Doppler which is used to telemetry measure the vertical profile of the water flow by the vetor synthesis method.The paper analyzes the principle of coherent pulse signal processing method of velocity measurement.According to the mechanism of the echo signal generation,the echo signal scattering superposition model is built,Monte Carlo method is used to compare and analyze the velocity measurement performance under different conditions.
