スマートアンテナのレジリエント運用のための不確定性モデル

抄録

This study proposes the uncertainty model for the resilient operation of our proposed smart antenna for the radio astronomy mission. The smart antenna recovers the antenna gain by compensating the deformation of the primary reflector using actuators installed in the sub-reflector. We have two important tasks for sufficient antenna gain recovery to achieve the resilient operation. The first is to achieve the recovery gain as much as possible. The second is to predict the recovered antenna gain, because we have no method to know the actual antenna gain except for the successful observation. In addition, the antenna gain recovery is degraded by several uncertainties including the measurement errors, install errors and so on. This manuscript describes the uncertainty modeling method for prediction the antenna gain recovery during the mission.
