Test of nonlinearity of time series is very important for nonlinear time series analysis and study of chaotic dynamics. This paper discusses various methods of test of nonlinearity of time series. Real-life sea clutter data are tested with the IAAFT method combined with redundancy. It is concluded that sea clutter comes from a nonlinear process by analyzing results of test. So nonlinear methods should use to study characteristic of sea clutter.
