In the previous paper, existing analysis methods for obtaining ocean wave characteristics were examined using echo signals from marine radar system. Several strong or weak points of the existing analysis methods were discussed. After discussions, the authors proposed a new method (MFT: Multiple Fourier Transform method) that would make it possible to obtain directional and lengthwise characteristics of wave systems propagating in different courses. In the present paper, they expand their method for estimating spreading characteristics of component waves as well as directional and lengthwise characteristics. They show that the proposed method can discriminate the directional, lengthwise and spreading characteristics of individual wave systems that compose a confused sea surfaces. They also discuss the analyzing accuracy of proposed method by comparing with that of 2-Dimensional Fourier Transform method.
