Abstract: The specialty of simulation of complex underwater acoustic signal is analyzed, and a validation method of simulation model is studied in accordance with the specialty. Following the order of considering one feature parameter first and then all feature parameters, the uniformity of simulation signal is analyzed by using of interval estimation and information fusing respectively. The method for validating simulation model of complex underwater acoustic signal is presented based on feature matching by estimating uniformity level of simulation signal. The application in simulation of underwater target echo shows that, the method is effectual for validating simulation model and helpful for raising the modeling efficiency.

Key words: acoustics, underwater acoustic signal, simulation model, validation, simulation credibility
