| 摘 要： | 为满足当前ADCP计量检定的迫切需求,根据ADCP在水池拖车试验检定时,换能器发射声波的主瓣、旁瓣与检定水池池壁、池底形成的几何关系,推导出了抑制旁瓣、不抑制旁瓣时检定水池的尺寸需求。以市场占有率最高的ADCP产品为研究对象,计算得出了不同工作频率ADCP对检定水池宽度和深度的理论值。导出的公式,进一步完善了ADCP计量检定的理论基础,为ADCP在室内可控环境下的检定规范制定及检定平台设施建设提供参考与借鉴。

| Abstract: | In order to meet the urgent requirements of the current ADCP calibration test,the size requirement of pool calibration is deduced for the cases of side lobe suppression and side lobe non-suppression according to the geometric relationships among the main lobe and side lobe of acoustic wave transmitted by the ADCP transducer,the pool wall,and the pool bottom,during the tank trailer test.Taking the ADCP products which occupies the highest market share as an example,the theoretical values of width and depth for different ADCP operational frequencies are computed.The formulas derived in this paper further improve the theoretical basis of ADCP measurement,providing a reference for making ADCP test criterion and constructing calibration platform in indoor controllable environment. |
