The active absorption of wave energy is a novel technique in the wave simulation system. However, it is a key problem to acquire the real-time characteristic parameters of the incidence wave. In this paper, a fast identification algorithm for regular wave motion is put forward based on Discrete Fourier Transform. The applicable scopes of the algorithm are also discussed. A number of simulations show that the proposed algorithm is effective and feasible.
