Noise Signal Simulation Method of Underwater Mobile Vehicle

In the conventional matched field processing, the influence of sound source motion is usually ignored, but in fact, the motion of sound source will cause the change of amplitude and phase of multi receiving sound field. If the simulation of simulation field can be improved to take into account the time relationship between signal, source velocity and displacement, the influence of motion on sound field can be introduced into MFP. On the basis of predecessors, this paper presents a simulation method of underwater vehicle noise signal when the receiving and transmitting points have relative motion, which provides a new idea for copy field calculation in passive location of moving sound source matching field.
