Wave simulation is a hot topic of Ocean Engineering. This article summarizes a method that can adapt to a wide range of random wave spectrums to emulate the waves environmentally. The method is converted to computer programs which are simple and convenient by language C and compute a large number of data used as data source to wave maker. The simulation result is verified by the experiment data. The test shows that the error between the analog spectrum and the target spectrum is lowest by using the numerical method presented in this paper. The acquisition of analog wave height data are used to estimate the spectrum by correlation function method. The numerical simulation method has a practical application value in the wave simulation.
