Abstract: The radial velocity of ocean radar is analyzed by integrating backscattered spectra by ocean surface waves in a certain period of time. This study examined the influence of the integration time on the accuracy of the estimation of tsunami inversion for various predominant periods of incoming tsunami waves based on numerical experiments performed with a simple bathymetry. It found that the accuracy depends significantly on the relation between the predominant period and the integration time. The results of numerical experiments concerning the 2011 Japan tsunami indicate that a longer integration time, which coresponds to higher velocity resolution, is permitted as long as the influence is small.
