Pcalを利用して補正できること、バックエンドにおけるチャンネル間の位相差は数度以内であること、ローパスフィルタの位相特性はほぼ直線で、かつ各局に使ったものの特性はほぼ同じであること、バックエンドにおける長期位相揺らぎの補正ができることを確認し、相対VLBIにおける大気位相揺らぎを見積もり、特に、衛星信号を受信した場合の相関位相揺らぎは短基線において5度以内、長基線において40度であったが、その原因を解明し、帯域消去フィルタを掛けることにより除去できることがわかった。これらの結果から、開発したVLBIシステムはSELENEの相対VLBI観測に十分な性能を持つことを確認している。","subitem_description_type":"Abstract"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
