Outline of Final Research Achievements

In this research, we have been working on system studies, ground clutter removal, and spatial resolution improvement technology by compressed sensing toward the realization of C-band phased array radar. In the examination of the antenna shape, it was found that the spherical shape is the best in terms of characteristics such as sidelobe level on azimuth and elevation angle dependence. In addition, as a result of examining the beam formation according to the MMSE concept, it was found that the side lobe level toward the ground can be suppressed to several tens of dB lower than that of the parabolic antenna. In addition, in the study of compressed sensing technology, it was shown that the same improvement in spatial resolution as reducing the beam width by several times can be obtained.

Academic Significance and Societal Importance of the Research Achievements

局地的な豪雨や竜巻など,地球温暖化や都市化の進行と共に,気象災害の防止に対する社会的な重要度は年々増している.本研究では,気象庁等での導入が期待されている次世代のC帯偏波フェーズドアレイ気象レーダの研究開発を行った.検討したレーダは,機械的な走査方法を一切用いない,マルチビームが可能な固定型のデジタルビームフォーミング技術を用いたフェーズドアレイレーダ方式であり,アレイ形状や信号処理,ビームスケジュール等のシステムシミュレーションを実施,その実現の可能性が示された.
