Radio Interferometer Simulator)を開発している。このシミュレータでは、VLBI基線で得られる天体の理想的なビジビリティに対して、大気位相揺らぎ、大気ΔsecZ効果、アンテナ位置誤差を位相部に重畳し、さらに熱雑音誤差をベクトル的に重畳することによってフリンジの時系列データを模擬し、計算結果をFITS-IDIフォーマットのファイルに出力することができる。本報告ではARISの持つ機能について紹介するとともに、次期スペースVLBI計画であるVSOP-2で位相補償観測を行った場合の開口合成像での改善効果についてARISと標準的な電波干渉計イメージ合成ソフトウエアであるAIPSによって検討した結果を報告する。","subitem_description_type":"Abstract"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
