Research Abstract |
We have developed an Imaging Wind Profiler (IWP) which enables us to observe the detailed structure of turbulence in the lower atmosphere. Frequency Domain Interferometry (FDI) is a technique to obtain high range resolution using the phase difference among receiving signals for various transmitting frequencies. We applied the FDI technique to LQ-7 which was upgraded to use five frequencies. From simultaneous observations with a 35-GHz cloud radar, we found the relation between the development of the atmospheric boundary layer and clouds. We have also developed digital receivers to enable Spatial Domain Interferometry (SDI).
