摘　　要：传递函数反映了系统输入输出之间的关系,是系统的固有特性。针对船舶这样的复杂系统,有效估计机械设备振动至辐射噪声的传递函数,有利于进行噪声源的识别、分离与量化。本文采用1种新的估计传递函数的方法—自适应估计传递函数方法,该方法计算简单准确,适合于工程应用。Transfer function,who describes the relation of input and output of system,is inherent feature.For complex ship system,effectively estimating transfer function from vibration of mechanical equipment to sound radiation is helpful to identification,separation and quantification of noise source.The text adopts a new estimate transfer function method—transfer function estimate based on adaptive method.It is fit for project application by computer simple and nicety.

关 键 词：传递函数 自适应 横向滤波器
