摘　　要：为了研究水下航行器探测的新途径,以水下航行器产生的尾流为研究对象,推导建立了水下航行器尾流感应电磁场的浅海数学模型,并利用高斯积分法对数学模型进行了数值求解和实例仿真计算,结果表明,水下航行器尾流感应电磁场具有频率低、远场衰减速度慢、传播距离远、持续时间长的特点,量级可观具有可探测性,可用于对水下航行器的探测。In order to provide the detection of submerged vehicle with new ideas, taking submerged vehicle wakes as the research object, the mathematical model of induced electromagnetic fields in shallow sea is pro- posed, which is solved using the Gaussian integral method. The instance simulation analysis shows that the in- duced electromagnetic field signals have low frequency, low decay rate in the far field, long transmission dis- tance, long existing time and considerable scale and detectable, which are significant in the detection of sub- merged vehicle.
