Moment methodunu kullanarak düşük sıyırma açılarında deniz kargaşası benzetimi

Scattering of electromagnetic waves from rough surfaces such as sea surface is an important problem for radar engineers, since a radar device should discriminate returns from the desired object (target) from those scattered by the undesired object, which is rough sea surface studied in this work. Since the sea surface is randomly changing with time for varying wind speeds, sea clutter problem becomes a stochastic problem. The main goal of this thesis is obtaining a model to calculate the backscattered power from rough sea surfaces at different environmental conditions for different radar parameters by using the Method of Moments (MoM) and Monte Carlo method. In the Monte Carlo approach, a set of randomly generated two-dimensional sea surfaces from two types of sea surface spectrums are used. Then, backscatter power calculations are obtained for each sea surface to calculate statistical results. Finally, by using the results obtained from this model, a comparative analysis with the empirical and statistical models in literature is carried out. It is concluded that an accurate and flexible sea clutter model for amplitude characterization is obtained which has a good agreement with the existing models.
