Abstract
The microwave scatterometer is one of the useful remote sensors for the sea surface measurement. The basic principle of the measurement is a scattering at sea surface. Therefore, it is necessary to understand the characteristic of the microwave scattering at sea surface in order to measure the sea surface condition. The purpose of this study is to investigate characteristics of microwave scattering under the various conditions in the experimental tank and also the consideration of measurement technique and data analysis method. Bragg scattering model is applied to the experimental condition, and the tendency in the measuring results of scattering strength is explained in this model. For the quantitative evaluation, however, it is necessary to more accurately grasp water surface profiles. The Doppler shift of scattering microwave has related to the speed of the scatterer.
