摘　　要：文章针对风和洋流等外界因素对现有的流速剖面仪对水测速考核精度产生影响的问题,提出了一种新的流速剖面仪对水测速精度考核方法,分析了该方法抗风和洋流干扰的原理。理论研究结果表明,该方法原理上可消除风速、风向、流速、流向等外界因素对流速剖面仪对水测速精度考核的影响。Aiming at the problem of influence of wind and ocean current on speed-precision measurement relative to current for ADCP, a new algorithm is proposed and the principle of its resistance against external interference and disturbancesis analyzed. The theoretical analysis result shows that the proposed method can eliminate the influence of wind and ocean current.
