中文摘要
本财政年度的结果证明,由于有关研究的实施,作为实验设计和制造的“VHF波Obihiro波带干涉仪”是具有规范功能的观察面。也就是说,它是与雷电放电有关的。结果表明,在空间分解能力较高时,成功定位的放电方向通常被称为“分支分离”,且几乎同时并行进行,可见VHF/UHF频段脉冲。通常情况下,虽然VHF/UHF波段的放电方式的可视化是利用窄带干涉法和时间延迟法来实现的,但是在这种方法中,不可能对树形的放电进行可视化,虽然这一研究应用在世界上是第一次实现,但他并不是夸大其词。Cons…更公平地说,所采用的是与雷击之前的放电方式相同的过程,以及未来几十年来人们认为有时不同的多重雷击的接连雷击的过程,结果清楚地表明,雷电是接连雷击的雷电的一个点,有时是几公里远的。此外,利用S的优势,还发现了许多观测事实,如对雷电放电起点的详细了解,对引起多重雷电的雷云中电荷结构的详细了解,对云中放电的一个发展方向的观察,以及对电波的观测。另一方面,它还成功地用超灵敏摄像机观测了红色雪碧,是一个联合研究人员。新西兰奥塔哥大学红精灵作为研究成果,特别是通过与D.Dowden教授的低周电磁波观测结果对比,得出了从雷云顶向电离层下部“放电”现象的结论,而且--通过对红精灵的观测,它的产生不依赖于一个地区或纬度,它成为一种非常普遍的现象已经变得清晰起来,并在北国、地中海等地相继找出了产生的原因。在美国地球物理会议杂志和电气电子工程师学会进行上述所有结果的官方公告印刷的同时,“甚高频波Obihiro带干涉仪”已被申请专利(申请号为日本专利申请号11-170666)。较少
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).
