A meteorological radar system with functions of polarimetric observation has been expected to be useful to meteorological fields. In this report, we evaluated the performance of such radars by computer simulations. We examined the performance of rain observation by a X-band dual-polarized radar. Although attenuation caused by rain at X-band was relatively large, deterioration in accuracy of the polarimetric observation was small as far as width of a region with intense rain of 20 mm/h was narrower than 20 km. These results are expected to be useful to the future design of high performance meteorological radars.
