摘　　要：分析了漂浮电缆受力情况,给出了平静海面下的接收信号表达式,得到了信号电压与电场强度的近似关系式。分析了海浪对漂浮电缆的影响,建立了海浪下的漂浮电缆模型,推导出水下航行器的拖带速度和线缆深度的关系,并且推导了海浪下漂浮电缆的接收信号表达式,得到了信号电压与电场强度的近似关系式,从而为水下航行器漂浮电缆收信性能的计算与应用提供了参考。First, the paper analyzes the method of submarine receiving signal in VLF in quietsea and the load-carrying capability of buoyant cable. It infers the receiving voltage under quiet sea depending on force analysis and gets the relation between signal voltage and E-field. Then, the sea wave effect to buoyant cable is analyzed, the model of buoyant cable under sea wave is set up, and antenna＇ s receiving signal voltage under sea wave is inferred. The relationship between the underwater vehicle towing speed and cable depth is derived, and the relation between signal voltage and E-field is achieved, thus to provide reference for the performance of submarine receiving signal.
