Fidelity Analysis of a Scale Target Simulator

On the basis of the common conclusion of echo characteristics of a submarine and the general recognition method for a torpedo, we take single-receiving multi-transmitting scale target simulator for example to analyze the en-gineering model of a scale target simulator and the key parameter in engineering implementation. Simulation results show that this simulator has insufficiencies in Doppler frequency shift, time delay, and target strength of multi-highlight structure echo, which infers a large space for improvement. This study may provide a reference for further optimization of the scale target simulation technology.
