| Outline of Final Research Achievements |
Range-imaging wind profiler radar (RWPR), which uses frequency less than several GHz, measures vertical profiles of wind velocity and turbulence with better height resolution than that of conventional wind profiler radar (WPR). Millimeter-wave cloud profiling radar (CPR) measures vertical profiles of cloud properties. In this research, we developed cloud resolving dual-frequency radar (CRDR) composed of 1.3 GHz RWPR and CPR. Adaptive clutter suppression (ACS), which is a technique for mitigating clutter, improves quality of data measured by WPR. We developed an ACS system that implements ACS capability in an existing WPR. By using data collected by CRDR, we carried out case studies of low-level clouds. It is suggested that CRDR can be a means that will be widely used for cloud observation.
