中文摘要
本财政年度的结果是,由于有关研究的执行,证明了作为实验设计和制造的“VHF波带广区域干涉仪”是具有规范功能的观测器平面。也就是说,它与雷电放电有关。可以得出结论,这是一个点,放电的方面,成功地定位由空间分解能力高时,通常被称为“分支分离”,并平行进行几乎同时具有可视化的VHF/UHF波段脉冲。通常,虽然放电方式的可视化是VHF/UHF频带,并且已经使用窄带干扰方法和时间滞后方法获得了形状,但是在该方法中,关于以树的形状进行的放电的可视化是不可能的,并且虽然该研究申请人等在世界上首次实现,但他并没有夸大。缺点 ...更多信息 随后,采取了与迄今为止的雷击放电方式相同的过程,以及几十年来被认为有时不同的多重雷击的连续雷击的过程,结果,清楚地表明了雷击是连续雷击的雷击点之前的雷击点,有时候它在几公里之外。此外,还利用其优势,获得了许多观测事实,如对雷电放电的起始点、引起多重雷电的雷云中电荷结构、云中放电的发展方向、电波观测等的详细了解。另一方面,它还成功地用超灵敏摄像机观察了红精灵,并且是联合研究人员。新西兰OTAGO大学的Red Sprite作为研究成果,特别是通过与D.Dowden教授的低周电磁波观测结果的对比,还应该提到得到了从雷暴云顶部到电离层下部是“放电”现象的结论,而且-这-通过Red Sprite的观测,其产生不依赖于地区或纬度,在北陆、地中海等地相继发现了其产生的原因。此外,在美国物理学会议杂志和电气和电子工程师协会上进行了所有上述结果的正式公告印刷的同时,“VHF波带广区域干涉仪”已经成为专利申请(申请号为日本专利申请No. 11 -170666)。少
英文摘要
The result of this fiscal year is the point that it has been proved that "VHF wave Obihiro zone interferometer" designed and made as an experiment was the spotter plane which has a function as specification because of the concerned research execution. That is, it emanates in connection with thunder electric discharge. It can be concluded that it is the point that the aspect of the electric discharge which succeeds in locateing by - space decomposition ability when high, is commonly called "branch separation", and progresses in parallel almost simultaneous has visualized VHF/UHF band pulse. Usually, although visualization of an electric discharge way was VHF/UHF band and shape has been taken using the narrowband interfering method and a time lag method, in which method, the visualization about the electric discharge which progresses in the shape of tree is impossible, and although this research applicant etc. was realized for the first time in the world, he is not an overstatement. Cons … More equently, what takes the same course as the electric discharge way of the thunderstroke preceded until now, and the course from which the succession thunderstroke of the multiplex thunderbolt which will come for some dozens years and was believed is sometimes different are taken, and, as a result, it is shown clearly thunderbolt being a point of the thunderstroke which the thunderbolt point of a succession thunderstroke precedes, and that it is sometimes several km away. Furthermore, many observation-facts are found out taking advantage of the advantage of *s, such as detailed understanding about the starting point of thunder electric discharge, and the electric charge structure in the thundercloud which causes a multiplex thunderbolt, a development aspect of the electric discharge in a cloud, and electric wave observation. On the other hand, it succeeds also in observation of Red Sprites with a super-sensitive video camera, and is a joint research person. The New Zealand OTAGO university Red Sprite serves as the research result which should also mention having obtained the conclusion that it is "electric discharge" phenomenon to the ionosphere lower part from the thundercloud top part especially by collation with Professor D.Dowden's low cycle electromagnetic wave observation result, moreover - this - By observation of Red Sprite, the generating is not dependent on an area or latitude, it becomes and that it is a very general phenomenon has become being clear and the cause that the generating is found out successively after that in Hokuriku, the Mediterranean, etc. In addition, while official announcement printing of all the above-mentioned results is carried out at the U.S.geophysics meeting magazine and Institute of Electrical and Electronic Engineers, "VHF wave Obihiro zone interferometer" has become under the patent application (application number Japanese Patent Application No.11-170666).
