Abstract

Abstract: Aiming at the characteristics that the output signal of outboard active decoy simulation model is non-stationary random signal, a simulation model verification method based on wavelet transform is proposed. The measured and simulated signals are decomposed into low frequency and high frequency parts by determining the wavelet function. For the low frequency part with stationary state, the characteristic data is obtained by parameter fitting with the least square method. For the high frequency part, AR model is used to fit the parameters, and the fitting parameters are used as the characteristic data, The correlation coefficient method is used to analyze and calculate the consistency of the characteristic data of low frequency and high frequenc. According to this strategy, the outboard active decoy simulation modelis verified using the external field test data under the typical application situation. The result shows that the method is helpful for improving the accuracy of model validation.
