In the previous paper, the authors applied the proposed MFT (Multiple Fourier Transform) method to the analyses of simulated sea surfaces composed of two different wave systems and radar echo signals from those sea surfaces. They showed that the MFT method can discriminate the directional and lengthwise characteristics of individual wave system that composes the confused sea surfaces, and that it can estimate the spreading characteristics of confused sea surfaces. They also show that the accuracy of analysis of MFT method is better compared with the results of 2-Dimensional Fourier Transform of PPI image. In the paper, they apply the MFT method to the analyses of radar echo obtained onboard ships of two different types sailing in a seaway. They show that the proposed method is able to discriminate directional and lengthwise characteristics of 2 different wave systems existing in actual seas.
