项目摘要

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).

本年度的成果是，通过相关研究的实施，作为实验设计、制作的“VHF波带广带干涉仪”已被证明是具有规格功能的观测机。与雷电放电相关，可以断定，在空间分解能力高的情况下成功定位的放电的情况，通常被称为“分支分离”，并且几乎同时并行地进行。可视化的VHF/UHF带脉冲通常使用窄带干涉法和时滞法来可视化放电方式为VHF/UHF带，但在该方法中，对在VHF/UHF带中进行的放电进行可视化。树的形状是不可能的，尽管本研究申请人等是世界上首次实现的，但他并没有夸大其辞。，以及在此过程中，将出现数十年的多重雷电的连续雷击，并且人们认为有时会有所不同，因此，可以清楚地表明，雷击是雷击中的一个点，而雷击点是一个雷击点。连续雷击在先，有时甚至在数公里之外。此外，利用*的优势发现了许多观测事实，例如详细了解雷电放电的起点和电荷结构。雷雨云导致另一方面，在利用超灵敏摄像机观测红色精灵方面也取得了成功，是新西兰的联合研究人员。 OTAGO大学Red Sprite作为研究成果，特别是与D.Dowden教授的低周期电磁波观测对照，得到了从雷云顶部到电离层下部“放电”现象的结论。结果，而且——这一点——通过对红精灵的观察，这种现象的产生不依赖于地区或纬度，它成为一种非常普遍的现象，这一点已经变得很清楚，并且随后陆续查明了产生的原因。此外，上述所有结果的正式公告印刷均在美国地球物理会议杂志和电气电子工程师学会进行，“VHF波带广区”干涉仪”已成为专利申请（申请号日本专利申请No.11-170666）。少
