Analysis and Simulation of Submarine Goal model Based on Torpedo Scale Target

Based on the simulation of highlights scale, the paper elaborates the generation mechanism of echo delay and mathematical model of virtual scale forming from the viewpoint of geometry-physics acoustics, and analyzes the characteristics of the engineering application of the model, finally verifies the feasibility by using of small-scale target replacing large-scale target for testing Torpedo-scale recognition function and sets accurate model for engineering application. The result also has some reference value for manufacturing of Torpedo-scale target, scale-acoustic decoy and other underwater acoustic simulation equipments.
