Increase of VSWR at VHP antenna was detected, when the second stage was burning. It has become clear that the level down of the ground reciever resulted not only from the scattering and attenation effects, but also from the impedance deviation effects of the antenna by exhaust plume., 資料番号: SA0125879000}, pages = {893--907}, title = {<論文>ロケット搭載アンテナの飛しょう中のVSWR特性}, volume = {16}, year = {1980} }
