| Outline of Final Research Achievements |
This study is devoted to development of humidity estimation method by using the carrier phase of L-band radar. The transmitted radio wave is detected by an independent receiver located away from the radar. The side-lobe transmission, which is regarded as the useless transmission, is positively used as the passive radar system. This new system is expected to estimate horizontal structure of humidity fluctuations.
In this study, the theoretical background of this new system was deeply discussed especially focusing on the error of oscillator and timing controller. The prototype system was assembled for the test experiment at the Shigaraki MU observatory.
