Abstract

 For naval radars, the concept of “the sea state” is very important. In this article, the sea waveequation and its shape of movement have been determined. Then, the waveforms of the sea waves have been reconstructed using the Feko software. After that, the RCS resulting from the impact of radar waves (with high range resolution radar) to sea level has been calculated in order to acquire returned signals from sea waves in antenna input. Subsequent to determining returned signals in the time domain and receiving these signals by the radar receiver, its first to forth moments are calculated. On the following, the feature space is formed and by using it sea waves are classified in four different modes. And finally, the precision of this suggested method has been measured by adding noise to returned signals from the sea level.
