Analysis on Ship Through Signature of Shallow Inshore Based on Single Hydrophone

For detection of shallow water channel, it needs to study the target characteristics in shallow water. As an important feature of the ship, ship through signature is simulated by the model of three highlights. In this model, this paper analyzes the effect of the source size and the working frequency band on the through signature curve. And it gets the through signature curve in shallow water and the relation between source size, speed and through signature by analysis of measured data, which effectively verifies the correctness of the simulation model.
