The paper describes the concepts of reconstruction of phase space, correlation dimension, Lyapunov exponent and power spectrum exponent. The calculations presented is based on experimental radar data which confirm the chaotic nature of sea clutter. In particular, the results of the calculations show that the first Lyapunov exponent of sea clutter is indeed positive. Such a result is an inherent characteristic of a chaotic process.
