| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | An observed signal of the Doppler weather radar includes not only weather echoes but also a ground clutter. For accurate observation of weather data, we need to remove the effect of the ground clutter. In this paper, we propose to model the spectrum of an observed signal as a mixture of density functions corresponding to a ground clutter and a weather echo. Where we apply the t density function to a ground clutter. Moreover, we apply the von Mises density function to a weather echo. To estimate the parameters of the density function, we apply the expectation-maximization (EM) algorithm in a maximum a posteriori (MAP) estimation with hyperparameters learned from the actual measurements of the ground clutter. Experimental results show that the proposed method works well in estimating the wind velocity, rainfall amount, and turbulence from the weather echo even when the spectrum of the weather echo is overlapped with that of the ground clutter in a lower frequency band. |
